Human Parathyroid Hormone (1-34)
Supplier: Anaspec Inc
Parathyroid hormone (PTH) regulates the metabolism of calcium and phosphate. PTH and PTH-related polypeptide (PTHrP) play important roles in calcium homeostasis of bone, kidney, breast, and placenta; they signal via the PTH/PTHrP and PTH2 receptors. PTH(1–34) administration suppresses cardiovascular calcification and down-regulates aortic osteogenic programs driven by diabetes and dyslipidemia.

390 MMP FRET Substrate V, Mca-DNP
Supplier: Anaspec Inc
Matrix Metalloproteinases (MMPs) are a large family of endopeptidases. Collectively, MMPs can degrade all kinds of extracellular matrix proteins, and can also process a number of bioactive molecules. They are known to be involved in the cleavage of cell surface receptors, the release of apoptotic ligands, and chemokine/cytokine inactivation. MMPs are also thought to play a major role in cell behaviors such as cell proliferation, migration (adhesion/dispersion), differentiation, angiogenesis, apoptosis, and host defense.
This peptide is a substrate for the MMP-12, macrophage elastase, Abs/Em = 325/393 nm. MMPs are considered to be critical mediators of both normal and pathological tissue remodeling processes.

GALA, Pore-Forming Peptide
Supplier: Anaspec Inc
GALA is a 30 amino acid synthetic peptide with a glutamic acid-alanine-leucine-alanine (EALA) repeat. It also contains a histidine and tryptophan residue as spectroscopic probes. This peptide was designed to explore how viral fusion protein sequences interact with membranes. It was used to study the importance of the helix length, hydrophobicity, and hydrophobic moment on the formation, structure, and function of ion channels. The membrane-interacting properties of GALA have been extensively documented. Investigations with analogs of cytotoxic peptides clarify the importance of peptide charge and the role of particular amino acids or arrays of amino acids in the conformation, membrane-binding affinity, and pore-forming abilities of these toxins.

MBP MAPK Substrate, Biotin
Supplier: Anaspec Inc
This is an N-terminally biotinylated peptide, with a phosphorylated Thr97. The sequence APRTPGGRR contains a native sequence derived from bovine myelin basic protein amino acids 95-98 (PRTP). The rest of the sequence is not derived from a native sequence, but is a synthetic construct. APRTPGGRR is specific for MAP kinases: p44MAPK [extracellular signal-regulated kinase 1 (ERK1)] and p42MAPK (ERK2). It contains the consensus sequence Pro-X-(Ser/Thr)-Pro that is recognized by MAP kinase. APRTPGGRR is the most efficient substrate for phosphorylation reaction by ERK and is phosphorylated by kinases on threonine 97 and can also be phosphorylated by MAPK p38.

Fluorescein di-b-D-galactopyranoside (FDG)
Supplier: Anaspec Inc
Fluorescein di-β-D-galactopyranoside (FDG) is one of the most sensitive fluorogenic substrates available for detecting β-galactosidase. The colorless and nonfluorescent FDG is hydrolyzed to highly fluorescent fluorescein, which exhibits excellent spectral properties (Ex/Em=492/520 nm) that match the optimal detection window of most fluorescence instruments. Galactosidase-catalyzed hydrolysis of FDG can be followed by fluorescence increase around 520 nm. Alternatively, FDG can also be used to detect β-galactosidase in a chromogenic mode since the enzymatic product (fluorescein) exhibits a large extinction coefficient (close to 100,000 cm-1mol-1). In general, fluorescence-based measurements can be several orders of magnitude more sensitive than absorption-based measurements. FDG has been widely used for identifying lacZ-positive cells with fluorescence microscopy and flow cytometry. FDG is also used to detect β-galactosidase expression in live cells. Fluorescence-based assays employing FDG are also reported to be 100 to 1000-fold more sensitive than radioisotope-based ELISAs.

Pannexin-1 Blocking Peptide
Supplier: Anaspec Inc
This is a Pannexin-1 (Panx1) mimetic blocking peptide. Pannexin-1 is a recently identified membrane protein that can form gap junction-like connections allowing intercellular passage of dyes when overexpressed in two adjacent oocytes or mammalian epithelial cell lines. Blockade of pannexin-1 in macrophage endogenously expressing the ATP-gated P2X7 receptor (P2X7R) blocks the initial dye uptake, but not the ionic current, and also blocks processing and release of interleukin-1beta (IL-1beta) in response to P2X7R activation.

Human Beta-Amyloid (1-39)
Supplier: Anaspec Inc
A number of Aß protein variants, differing only at their carboxy terminus (1-39, 1-40, 1-42 and 1-43), are identified as the major components of the cerebral amyloid deposits in Alzheimer’s disease. The length of the C-terminus is a critical determinant of the rate of amyloid formation (“kinetic solubility”), with only a minor effect on the thermodynamic solubility. Amyloid formation by the kinetically soluble peptides (e.g. 1-39) can be nucleated, or “seeded” by peptides which include the critical C-terminal residues (1-42, 26-42, 26-43, 34-42).

Pig Protegrine-1 (PG-1)
Supplier: Anaspec Inc
This peptide is Protegrin-1 (PG-1) with a modified C-terminal amide. PG-1 is an 18-amino-acid beta-hairpin antimicrobial peptide found in porcine leukocytes and belongs to the cathelicidin family. PG-1 exhibits broad-spectrum activity unaffected by extracellular NaCl concentrations and is capable of inactivating numerous bacterial strains, Candida albicans, and some enveloped viruses. The efficacy is strongly dependent upon the existence of two disulfide bonds that stabilize the beta-sheet structure.

Plasmodium PfCSP
Supplier: Anaspec Inc
The P. falciparum circumsporozoite protein (PfCSP) is the most abundant antigen expressed on the surface of P. falciparum sporozoites. This pre-erythrocytic antigen contains a stretch of 6 highly conserved, immunodominant tetrapeptide repeats (NANP) in the middle, while its N- and C-terminal regions contain two crucial protective regions termed RI and RII-plus, respectively. Both play key roles during parasite invasion. PfCSP has been the main target antigen in the development of preerythrocytic malaria vaccines, including subunit proteins with adjuvants or attenuated viral platforms. Studies show that high titers of antibodies directed to PfCSP are believed to interrupt the invasion of hepatocytes by blood-borne sporozoites, thereby abrogating the development of blood-stage malaria.
