Anti-SAA Mouse Monoclonal Antibody [clone: 607]
Supplier: Genetex
The serum amyloid A family comprises a number of differentially expressed apolipoproteins, acute-phase SAA1 and SAA2, the former being the major component in plasma and constitutive SAAs. Although the liver is the primary site of synthesis of both SAA types extrahepatic production has been reported. The in vivo concentrations increase by as much as 1000 fold during inflammation. Several studies have expressed its importance in the diagnosis and monitoring of various diseases. Pathological SAA values are often detected in association with normal CRP concentrations; SAA rises earlier and more sharply than CRP. Recently, a broader view of SAA expression and function has been emerging. Expression studies show production of SAA proteins in histologically normal, atherosclerotic, Alzheimer, inflammatory, and tumour tissues. SAA has been found to have binding sites for high density lipoproteins, calcium, laminin, and heparin/heparin sulphate. Also adhesion motifs were identified and new functions affecting cell adhesion, migration, proliferation, and aggregation were discovered. These findings emphasize the importance of SAA in various physiological and pathological processes including inflammation, atherosclerosis, thrombosis, AA-amyloidosis, rheumatoid arthritis, and neoplasia. SAA has also a number of immunomodulatory roles, it can induce chemotaxis and adhesion molecule expression, has cytokine-like properties and can promote the upregulation of metalloproteinases. It enhances the binding of high density lipoprotein to macrophages and thus helps in the delivery of lipids to sites of injury for use in tissue repair, it is thus thought to be an integral part of the disease process.

Anti-BRCA1 Mouse Monoclonal Antibody [clone: MS13]
Supplier: Genetex
BRCA1 (breast and ovarian cancer susceptibility protein 1) is a RING finger protein containing a BRCT domain. BRCA1 exists as a heterodimer with 22 possible isoforms. The full length protein has a reported molecular weight of 208 kD. BRCA1 localizes to the mitotic spindle microtubules, centriole walls, pericentriolar fibers at centrosomes. Unphosphorylated BRCA1 localizes on chromosomes from metaphase through telophase; phosphorylated BRCA1 resides in inner chromosomal structure, centrosome, cleavage furrow during prophase through telophase, and relocalizes to the perinuclear region when cells are subjected to IR or UV radiation in S phase. BRCA1 acts as a tumor suppressor and can function as a secreted growth inhibitory protein, participate in transcription coupled repair of oxidative DNA damage, X-chromosome inactivation, and can function as a E3 ubiquitin ligase. BRCA1 can be transcriptionally downregulated by Ets-2, Brg-1, and Hmga-1. BRCA1 can be modified by glycosylation, ubiquitination and phosphorylation by CDK4, ATM/ATR, cdk2, and hChk2. The BRCA1 protein has been reported to interact with RNA polymerase II holoenzyme and BARD1. BRCA1 contains at least two nuclear localization signals and is proposed to be a tumor suppressor protein. It is a serine phosphoprotein that undergoes hyperphosphorylation during late G1 and S phases of the cell cycle and is transiently dephosphorylated early after M phase. BRCA1 protein alters in a qualitative and quantitative manner during cell cycle progression. The amount of BRCA1 protein is highest during S phase and remains elevated toward G2 / M, before it declines in early G1 phase. Inherited loss of BRCA1 function confers an increased susceptibility for both breast and ovarian cancer.

Agarose multipurpose, white powder for molecular biology
Supplier: MP Biomedicals
Agarose is a natural polysaccharide isolated from agar or agar-bearing marine algae. Its physical and chemical properties are particularly suited for use as a gel medium for diffusion and electrokinetic movement of biomolecules. Agarose is essentially biologically inert and forms relatively clear, transparent gels. Agarose based gels offer several advantages: High gel strength permits use of low concentrations. The macroporous nature of the gels allows rapid diffusion of high molecular weight molecules. Agarose is Non-toxic. Agarose gels are thermally reversible facilitating sample recovery. Staining and destaining may be done rapidly with minimal background. Because agarose forms macroporous gels that are electrically nonionic, it is an excellent medium for Isoelectric Focusing (IEF). A selection of different formulated agaroses with specific qualities for unique applications are available from MP.
Multipurpose Agarose is a versatile high gel strength agarose, especially designed for a wide range of molecular biology techniques.

Anti-CRYAB Mouse Monoclonal Antibody [clone: 10D5F4]
Supplier: Prosci
Crystallin, alpha B.Crystallins are separated into two classes: taxon-specific, or enzyme, and ubiquitous. The latter class constitutes the major proteins of vertebrate eye lens and maintains the transparency and refractive index of the lens. Since lens central fiber cells lose their nuclei during development, these crystallins are made and then retained throughout life, making them extremely stable proteins. Mammalian lens crystallins are divided into alpha, beta, and gamma families; beta and gamma crystallins are also considered as a superfamily. Alpha and beta families are further divided into acidic and basic groups. Seven protein regions exist in crystallins: four homologous motifs, a connecting peptide, and N- and C-terminal extensions. Alpha crystallins are composed of two gene products: alpha-A and alpha-B, for acidic and basic, respectively. Alpha crystallins can be induced by heat shock and are members of the small heat shock protein (sHSP also known as the HSP20) family. They act as molecular chaperones although they do not renature proteins and release them in the fashion of a true chaperone; instead they hold them in large soluble aggregates. Post-translational modifications decrease the ability to chaperone. These heterogeneous aggregates consist of 30-40 subunits; the alpha-A and alpha-B subunits have a 3:1 ratio, respectively. Two additional functions of alpha crystallins are an autokinase activity and participation in the intracellular architecture. Alpha-A and alpha-B gene products are differentially expressed; alpha-A is preferentially restricted to the lens and alpha-B is expressed widely in many tissues and organs. Elevated expression of alpha-B crystallin occurs in many neurological diseases; a missense mutation cosegregated in a family with a desmin-related myopathy.

ß-Nicotinamide adenine dinucleotide phosphate (NADP-Na2, oxidized form) ≥98%, white powder
Supplier: MP Biomedicals
β-NADP is a coenzyme necessary for the alcoholic fermentation of glucose and the oxidative dehydrogenation of other substances. It occurs widely in living tissue, especially in the liver. Nicotinic acid can be converted to nicotinamide in the body and, in this form, is found as a component of two oxidation-reduction coenzymes: nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). The nicotinamide portion of the coenzyme transfers hydrogens by alternating between oxidized quaternary nitrogen and a reduced tertiary nitrogen. NADP is an essential coenzyme for glucose-6-phosphate dehydrogenase which catalyzes the oxidation of glucose-6-phosphate to 6-phosphogluconic acid. This reaction initiates metabolism of glucose by a pathway other than the citric acid cycle. This route is known as the hexose phosphate shunt or phosphogluconate pathway. Other enzymes which utilize NADP as a coenzyme are: Alcohol dehydrogenase:NADP dependent; Aromatic ADH:NADP dependent; Ferredoxin-NADP reductase; L-Fucose dehydrogenase; Gabase; Galactose-1-phosphate uridyl transferase; Glucose dehydrogenase; L-Glutamic dehydrogenase; Glycerol dehydrogenase:NADP specific; Isocitric dehydrogenase; Malic enzymes; 5,10-Methylenetetrahydrofolate dehydrogenase; 6-Phosphogluconate dehydrogenase and Succinic semialdehyde dehydrogenase.

Supplier: MP Biomedicals
Sodium phosphate is a reagent with very high buffering capacity that is widely used in molecular biology, biochemistry, and chromatography. Sodium phosphate occurs in several forms: monobasic (NaH2PO4), dibasic (Na2HPO4), and tribasic (Na3PO4). Most neutral sodium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH.
Sodium phosphate monobasic, Monohydrate is used as sequestrant, emulsifier and buffer in foods; as mordant in dyeing; for weighting silk in tanning; in manufacture of enamels, ceramics, detergents, boiler compounds; as fireproofing agent; in soldering and brazing instead of borax; as reagent and buffer in analytical chemistry; cathartic; laxative. A table for preparation of 0.1 M sodium phosphate buffer at 25 °C using various proportions of sodium phosphate monobasic and sodium phosphate dibasic has been published. A study of the effect of freeze-thaw storage cycles on proteins in sodium phosphate and potassium phosphate buffer solutions has been reported. The effect of 5 mM sodium phosphate on the efficacy of electrospray ionization (ESI) ion mobility spectrometry (IMS) analysis has been evaluated. A protocol for the purification of pyrogen-free mouse IgG1 monoclonal antibodies which uses 10 mM sodium phosphate (pH 7.4) has been published. An ion-pairing HPLC method for the analysis of 5-aminosalicylic acid has been reported. A TLC method for separation of nucleotide sugars in the study of glycosyltransferase activity has been published.

Anti-p75NTR Mouse Monoclonal Antibody [clone: MC192]
Supplier: Biosensis
"Monoclonal antibody MC192 against the rat low affinity nerve growth factor receptor (p75NTR) is derived from the fusion of Sp2/0-Ag 14 myeloma cells with mouse immune splenocytes. MC192 monoclonal antibody was originally generated by Chandlers et al. p75NTR was originally discovered as a low affinity nerve growth factor receptor. Later it was found that it was the receptor for all neurotrophins. It mediates signals of neurotrophins for neuronal survival, apoptosis, neurite outgrowth and synaptic plasticity. Recently, it has been revealed that p75NTR is not only acts as the receptor for neurotrophins but also the receptor for many other pathological ligands such as prions, rabies virus and amyloid beta. p75NTR also acts as a co-receptor for NOGO which mediates inhibitory signals of myelin associated protein. p75NTR is highly expressed in a number of non-neuronal and neuronal cells including motor neurons during development and also in damaged neurons. MC192 recognizes the extracellular domain of the neurotrophin receptor p75NTR in rat. MC192 antibody may be used for immunocytochemical localisation of rat cells expressing p75NTR, ELISA and western blot. This antibody has also been used for the construction of the MC192-saporin immunotoxin for specific elimination of neuronal populations in basal forebrain cholinergic neurons to generate an animal model for Alzheimer's disease. Using Flow Cytometry, this antibody has frequently been employed for panning to isolate p75NTR-expressing rat cells. MC192 has a potential use as the ligand for gene delivery into p75NTR-expressing rat cells via a receptor-mediated mechanism.

Cycloheximide, white powder cell culture reagent
Supplier: MP Biomedicals
Cycloheximide is a glutarimide antibiotic derived from a microbial source. Cycloheximide is an antibiotic which is very active against many molds, yeasts, and phytopathogenic fungi. It exhibits somewhat lower activity against bacteria and certain fungi. Control of various molds and fungi in gelatin-based photographic emulsions, photoengraving glues, and other light-sensitive products is suggested.
Cycloheximide is used in plant research to study disease resistance and as an ethylene stimulant, useful in studies involving fruit and leaf production. It is also used in bacteriological media to isolate or count bacteria in the presence of yeast and molds; Used in protein synthesis in apoptosis; Gene expression; Glycogenolysis, gluconeogenesis and ureogenesis in isolated rat hepatocytes; Studies involving steroidogenesis; Used in plant regulation and as a quality control measure by the food and beverage industry.
Cycloheximide (CHX) is an antibiotic produced by S. griseus. Its main biological activity is translation inhibition in eukaryotes resulting in cell growth arrest and cell death. CHX is widely used for selection of CHX-resistant strains of yeast and fungi, controlled inhibition of protein synthesis for detection of short-lived proteins and super-induction of protein expression, and apoptosis induction or facilitation of apoptosis induction by death receptors. Cycloheximide inhibits peptide synthesis in eukaryotic organisms but not in prokaryotes. Protein synthesis is blocked by the interaction of cycloheximide with the translocase enzyme. This interaction prohibits the translocation of messenger RNA on the cytosolic, 80S ribosomes without inhibiting organelle protein synthesis. Cycloheximide is also known to induce FAS/FAS Ligand apoptosis, and triggers apoptosis in HL-60 cells, T-cell hybridomas, Burkitt's lymphoma cells in addition to a variety of other cell types. Cycloheximide will also delay or inhibit apoptosis induced by other agents.

Performance Check Solution for US EPA Method 508, SPEX CertiPrep
Supplier: SPEX CERTIPREP LLC
Pesticides, PCBs and Herbicides
The EPA is tasked with the monitoring of environmental systems as they pertain to contamination and human health. The methods issued by the EPA are created to respond to specific toxins or persistent organic pollutants (POPs) found in environmental samples such as soil, source water, drinking water, and waste. In particular, pollutants such as polychlorinated biphenyls (PCBs), which were in widespread industrial use up until their restriction, are of concern due to their stable and persistent nature in the environment. Another group of chemicals of high concern is the hundreds of commercial pesticides and herbicides in use in the world today. Pesticides, from algaecides to virucides, are used in large quantities in industrial and private agriculture. The concern over human pesticide exposure over the past few decades has led to extensive monitoring of these pesticides. It has been reported that over 98% of insecticides and 95% of herbicides affect areas other than their intended target product. It is essential that monitoring agencies have accurate standard mixes to measure the pesticide levels in the environment.
Many new pesticides are now being tested using highly sensitive LC/MS techniques, in addition to traditional GC techniques, to determine minute amounts of residue in environmental samples and food products.
At SPEX CertiPrep, we facilitate ease of monitoring and testing of pesticides by creating pesticide test mixes to suit your monitoring needs. SPEX CertiPrep is the leader in offering pesticide standards designed to work within EPA, AOAC and FDA analytical testing methods using all of the leading analytical techniques: LC, LC/MS, GC, and GC/MS. Many pesticide standard mixes are readily available in our catalog along with a large list of single pesticide standards. In addition, custom pesticide mixes can be made to your specifications to create a mix that meets your needs.
US EPA Method 508 is an analytical method for the monitoring of organochlorine pesticides and PCBs in drinking water and ground water by GC/ECD
