Pax genes contain paired domains with strong homology to genes in Drosophila, which are involved in programming early development. Lesions in the Pax-6 gene account for most cases of aniridia, a congenital malformation of the eye, chiefly characterized by iris hypoplasia, which can cause blindness. Pax-6 is involved in other anterior segment malformations besides aniridia, such as Peters anomaly, a major error in the embryonic development of the eye with corneal clouding with variable iridolenticulocorneal adhesions. The Pax-6 gene encodes a transcriptional regulator that recognizes target genes through its paired-type DNA-binding domain. The paired domain is composed of two distinct DNA-binding subdomains, the amino-terminal subdomain and the carboxy-terminal subdomain, which bind respective consensus DNA sequences. The human Pax-6 gene produces two alternatively spliced isoforms that have the distinct structure of the paired domain.

This antibody reacts with both SUMO2 and SUMO3. The small ubiquitin-related modifier (SUMO) proteins, which include SUMO1, 2 and 3, belong to the ubiquitin-like protein family. Like ubiquitin, the SUMO proteins are synthesized as precursors that undergo processing before conjugation to target proteins. Also, both utilize the E1, E2 and E3 cascade enzymes for conjugation. However, SUMO and ubiquitin differ with respect to targeting. Ubiquitination predominantly targets proteins for degradation, whereas sumoylation targets for a variety of cellular processing, including nuclear transport, transcriptional regulation, apoptosis and protein stability. The unconjugated SUMO1/2/3 proteins localize to the nuclear membrane, nuclear bodies and cytoplasm, respectively. SUMO1 utilizes Ubc9 for conjugation to several targets, which include MDM2, p53, PML and RanGap1. SUMO2/3 contribute to a greater percentage of protein modification than does SUMO1 and they can form polymeric chains. In addition, SUMO3 regulates beta-Amyloid generation and may be critical in the onset or progression of Alzheimer’s disease.

The pro-inflammatory cytokine IL-1 induced cellular response requires IL-1 receptor complex including IL-1RI and IL-1RAcP. MyD88 has been identified as an adapter molecule in the IL-1 signaling pathway. MyD88 associates with and recruits IRAK to the IL-1 receptor complex in response to IL-1 treatment and dominant negative form of MyD88 attenuates IL-1R-mediated NF-kB activation. MyD88 is also employed as a regulator molecule by IL-18 receptor and human Toll receptor, which are members in the Toll/IL-1R family of receptors. Targeted disruption of the MyD88 gene results in lose of cellular responses to IL-1 and IL-18, and MyD88-deficient mice lack responses to bacterial product LPS that employs Toll-like receptors 2 and 4 (TLR2 and TLR4) as the signaling receptors. MyD88 is a general adapter protein for the Toll/IL-1R family of receptors and plays an important role in the inflammatory response induced by cytokines IL-1 and IL-18 and endotoxin. MyD88 gene is expressed in many tissues.

Interleukin-33 (IL-33) is a recently identified member of the IL-1 family of cytokines whose other members include IL-1ab, IL-1Ra and IL-18. Its receptor has been shown to be ST2, an IL-1 receptor family member that also acts as a negative regulator of TLR-IL-1R signaling and IL-1R accessory protein (IL-1RAcP). Receptor binding of IL-33 activates NF-kB and MAP kinases and induces the expression of TH2-associated cytokines such as IL-4, IL-5 and IL-6. Prolonged IL-33 treatment of mice led to the development of eosinophilia, splenomegaly, and severe pathological changes in mucosal organs such as lungs, esophagus and small intestine. Recent experiments have shown that IL-33 can also co-localize with heterochromatin and possesses transcriptional repressor activities, indicating that IL-33 may function as both a proinflammatory cytokine and an intracellular nuclear factor with transcriptional regulatory properties. Despite its predicted molecular weight, IL-33 will often run at higher molecular weight in SDS-PAGE.

Serine kinase that plays an essential role in the NF-kappa-B signaling pathway which is activated by multiple stimuli such as inflammatory cytokines, bacterial or viral products, DNA damages or other cellular stresses. Acts as part of the canonical IKK complex in the conventional pathway of NF-kappa-B activation and phosphorylates inhibitors of NF-kappa-B on 2 critical serine residues. These modifications allow polyubiquitination of the inhibitors and subsequent degradation by the proteasome. In turn, free NF-kappa-B is translocated into the nucleus and activates the transcription of hundreds of genes involved in immune response, growth control, or protection against apoptosis. In addition to the NF-kappa-B inhibitors, phosphorylates several other components of the signaling pathway including NEMO/IKBKG, NF-kappa-B subunits RELA and NFKB1, as well as IKK-related kinases TBK1 and IKBKE. IKK-related kinase phosphorylations may prevent the overproduction of inflammatory mediators since they exert a negative regulation on canonical IKKs. Also phosphorylates other substrates including NCOA3, BCL10 and IRS1. Within the nucleus, acts as an adapter protein for NFKBIA degradation in UV-induced NF-kappa-B activation.

STAT2 is a member of the STAT family of transcription factors. Unlike other STATs, STAT2 is unique as it can only be activated by interferons (IFNs). STAT2 is a critical component in mediating many IFN-stimulated biological activities including antiproliferation and antiviral responses. Upon IFN treatment, STAT1 and STAT2 become tyrosine phosphorylated, assemble as heterodimers that bind IRF9 to form the ISGF3 complex. This complex translocates to the nucleus, binds to promoters of IFN-stimulated genes and mediates gene transcription. Consequently, mutations in STAT2 or loss of STAT2 expression leads to impairment in IFN signal transduction and gene activation. IFN-alpha is an approved drug for the treatment of several forms of cancer. Yet only a subset of patients who receive IFN-alpha therapy benefit from the treatment. Given that STAT2 is activated by IFNs, it is important to define if the reduced or lack of antitumor effects seen in cancer patients on IFN therapy is due to in defects in STAT2 function. STAT2 pS734 antibody is ideal for researchers focused in cancer and transcripton factor research.

UCHL1 antibody recognizes Ubiquitin C-terminal hydrolase 1 (UCHL1) which is also known as ubiquitin carboxyl esterase L1, ubiquitin thiolesterase, neuron-specific protein PGP9.5 and Park5. It was originally identified as a major component of the neuronal cytoplasm from 2-dimensional gel analysis of brain tissues, and was given the name PGP9.5. It was later found that ubiquitin C-terminal hydrolase enzyme activity was associated with the PGP9.5 protein. The ubiquitin C-terminal hydrolases cleave ubiquitin from other molecules. Regulation of the ubiquitin pathway is very important and many disease states are associated with defects in this pathway. Genetic knockout of UCHL1 in mice results in a motor neuron degeneration similar to the spontaneous gracile axonal dystrophy (gad) mutant mice. Point mutations in the UCHL1 gene are associated with some forms of human Parkinson's disease. Since UCHL1 is heavily expressed in neurons, it is released in large amounts following injury or degeneration, so the detection of UCHL1 in CSF and other bodily fluids can be used as a biomarker.
Therefore, UCHL1 monoclonal antibody is ideal for investigators involved in Neuroscience.

Tricine was first prepared by Good for use as a buffer for chloroplast reactions. It is structurally similar to Tris, but is much less inhibitory at high concentrations. For ATP assays using firefly luciferase, tricine buffer at 25 mM was found to be the best of ten common buffers tested.
Tricine is used as buffer component for separation of low molecular weight peptides. Tricine can be used in cryopreservation medium for the preservation of tissues and organs. Cryopreservation depends on the physical and chemical characteristics of the preservation medium used. The pH values and pK values for tricine/DMSO mixtures has been reported down to -20 °C. Tricine has been found to be an efficient scavenger of hydroxyl radicals in a study of radiation-induced membrane damage. Tricine is typically the buffer of choice in SDS-PAGE systems when separating proteins in the range of 1 to 100 kDa.
A buffer may be prepared by titrating with sodium hydroxide to the desired pH, using about a half-equivalent of NaOH.

Influenza A virus is a major public health threat, killing more than 30, 000 people per year in the USA. In early 2009, a novel swine-origin influenza A (H1N1) virus was identified in specimens obtained from patients in Mexico and the United States. The virus spread quickly around the world and on June 11, 2009, the World Health Organization declared it a pandemic. Influenza A virus has one of sixteen possible Hemagglutinin (HA) surface proteins and one of nine possible Neuraminidase (NA) surface proteins. The Hemagglutinin protein facilitates viral attachment while Neuraminidase is involved in viral release. These proteins also elicit immune responses that prevent infection or independently reduce viral replication. The genetic make-up of this swine flu virus is unlike any other: it is an H1N1 strain that combines a triple assortment first identified in 1998 including human, swine, and avian influenza with two new pig H3N2 virus genes from Eurasia, themselves of recent human origin. The distinct antigenic properties of the new swine influenza virus compared with seasonal influenza A (H1N1) virus suggest that human immunity against new swine influenza virus is limited, although the age distribution of reported cases suggests some degree of protection in older age groups.

Cytokeratins, also called keratins or simply CKs, are a family of fibrous structural proteins and a major structural component in the outer layer of human skin, as well as hair and nails.  There are 20 human epithelial keratins which can be divided into two subfamiles: acidic and basic (more recent human genone sequencing has identified an additional 20 members). The formation of cytokeratin intermediate filaments requires the pairing of at least one acidic and one basic subfamily member. Members of the same keratin subfamily share extended sequence homology while members of different subfamilies show only limited sequence homology.

This antibody is specific for the 56.5kDa (CK10), 50kDa (CK14), 50kDa (CK15), 48kDa (CK16), and 40kDa (CK19) keratins of the acidic (Type I or LMW) subfamily. Many studies have shown the usefulness of CKs as markers in cancer research and tumor diagnosis, as epithelial tumors generally maintain the same CK expression patterns as their counterpart normal tissue. Clone AE1 is commonly used with clone AE3 as a pan cytokeratin antibody cocktail (Cat No V2330).

Catecholamine, a term used for the hormone adrenaline and its sequentially hydroxylated form noradrenaline, is involved in fight or flight responses. Noradrenaline is released from the post ganglionic sympathetic nerve endings and exerts its effects locally in the immediate vicinity of its release. In the CNS, noradrenaline is involved in a number of physiological responses including mood, sleep regulation, alertness and arousal, both cognitive and non-cognitive expression of behaviors, and control of the endocrine and autonomic nervous systems. Peripherally, noradrenaline is present in sympathetic nerve endings and has full control of the sympathetic nervous system. Noradrenaline released from pre-synaptic nerve terminals is reabsorbed (70-90%) by noradrenaline transporters and its biological effects are terminated. The noradrenaline transport via noradrenaline transporters is an active, Na+/Cl- dependent transport process mediated by noradrenaline transporters. Noradrenaline transporters constitute the primary mechanism for inactivation of synaptically released noradrenaline, are targets for multiple antidepressants and psychostimulants, and are deficient in affective and autonomic disorders. In rat brain, noradrenaline transporter is expressed in noradrenergic neuronal somata, axons and dendrites, and hippocampus and cortex, but is absent from epinephrine- and dopamine-containing neurons. At least 13 genetic variations have been reported in the noradrenaline transporter protein that affect noradrenaline re-uptake and concentrations in cerebrospinal fluid in humans. The association between these genetic variations in noradrenaline transporters and several psychiatric and cardiovascular disorders is just emerging. Recently, a single amino acid mutation (hNET-A457P) showed deficiency in noradrenaline transport in an orthostatic intolerance patient.

This mAb recognizes a protein of 41kDa, which is identified as TDP2, or ETS1 associated protein II. It is a member of a superfamily of divalent cation-dependent phosphodiesterases. The encoded protein associates with CD40, tumor necrosis factor (TNF) receptor-75 and TNF receptor associated factors (TRAFs), and inhibits nuclear factor-kappa-B activation. This protein has sequence and structural similarities with APE1 endonuclease, which is involved in both DNA repair and the activation of transcription factors. DNA repair enzyme that can remove a variety of covalent adducts from DNA through hydrolysis of a 5'-phosphodiester bond, giving rise to DNA with a free 5' phosphate. Catalyzes the hydrolysis of dead-end complexes between DNA and the topoisomerase 2 (TOP2) active site tyrosine residue. Hydrolyzes 5'-phosphoglycolates on protruding 5' ends on DNA double-strand breaks (DSBs) due to DNA damage by radiation and free radicals. The 5'-tyrosyl DNA phosphodiesterase activity can enable the repair of TOP2-induced DSBs without the need for nuclease activity, creating a 'clean' DSB with 5'-phosphate termini that are ready for ligation. Has also 3'-tyrosyl DNA phosphodiesterase activity, but less efficiently and much slower than TDP1. May also act as a negative regulator of ETS1 and may inhibit nuclear factor-kappa-B activation.
