Human [Lys(Ac)382]-p53 (361-393), Biotin, AnaSpec

Supplier: Anaspec Inc

This peptide is derived from amino acid residues 372-389 of human p53 tumor suppressor protein and is acetylated at Lys382. It is biotinylated at its N-terminus through a 6-carbon LC linker. Activated p53 functions to induce cell cycle arrest and apoptosis in response to signals such as DNA damage. Acetylation of p53 reduces ubiquitination by MDM2 and increases p53 half-life in vivo.

HCV Protease Substrate, DABCYL-EDANS

Supplier: Anaspec Inc

This peptide is a HCV protease substrate incorporating an ester bond between residues P1 and P1. Due to ready transesterification of the scissile bond to the acyl-enzyme intermediate, this substrate shows very high kcat/Km values, enabling detection of activity with subnanomolar nonstructural protein 3 (NS3 protease) concentrations. It is widely used for the continuous assay of NS3 protease activity. Substrate cleavage is proportional to the enzyme concentration with a detection limit for NS3 between 1 nM and 250 pM. Upon cleavage of this substrate, fluorescence can be monitored at Abs/Em = 355/500 nm.

Human [Lys22]-beta-Amyloid (1-42)

Supplier: Anaspec Inc

This is amino acids 1 to 42 fragment of the beta-amyloid peptide, with lysine substituted for glutamic acid at position 22 found in Italian families with Alzheimer's disease. The Italian mutation of beta -amyloid 1 to 42 (E22K) aggregates more rapidly and with more potent neurotoxicity than wild-type beta-amyloid (1-42). The formation of a salt bridge between Lys22 and Asp23 in the minor conformer might be a reason why E22K is more pathogenic than wild-type beta-amyloid (1-42).

Rat C-Peptide-1

Supplier: Anaspec Inc

This is amino acid sequence of rat C-peptide-1. C-peptide binds specifically to cell surfaces, probably to a G protein-coupled surface receptor, with subsequent activation of Ca2+-dependent intracellular signaling pathways. It also stimulates Na+-K+-ATPase and endothelial nitric oxide synthase activities. Rat C-peptide was found to diminish glucose-stimulated insulin release in rats both in vivo and in vitro.

EndoClear™ Human Recombinant alpha-Synuclein (from E. coli)

Supplier: Anaspec Inc

Full-length Recombinant human alpha-synuclein (GenBank Accession # NP_000336) was expressed in E. coli., and purified from bacterial lysate using proprietary method. Endotoxin was further removed by proprietary technique.
α-Synuclein is a major component of Lewy bodies in the affected neurons in Parkinson's disease. This protein has a mass of 14.5 kDa (140 amino acids long) and consists of a conserved degenerative amino-terminal domain and an acidic carboxyl-terminal with higher sequence divergence. α-Synuclein is predominantly expressed in brain, specifically in cerebellum, thalamus, neocortex, hippocampus, and striatum regions. Other tissues express α-Synuclein at very low levels. The physiological role of α-synuclein is not yet well understood. However, the presence of imperfect KTKEGV lipid interacting repeats suggests that it may be involved in synaptic vesicle homeostasis.

EMP17, FITC-LC labeled, FITC (Fluorescein Isothiocyanate)

Supplier: Anaspec Inc

This is a fluorescent (FITC)-labeled Erythropoietin (EPO)-mimetic peptide (EMP17), Abs/Em=494/520 nm. Erythropoietin (EPO) is the hormone involved in red blood cell production, which activates its receptor by binding to the receptor's extracellular domain and presumably dimerizing two receptor monomers to initiate signal transduction. EMP contains two potentially reactive amines, one at the amino terminus of the peptide and one in the side chain of the single lysine within the peptide sequence.

Hen Elafin

Supplier: Anaspec Inc

This is a fragment of the elafin (elastase-specific inhibitor), an antiproteinase and antimicrobial (gram-positive and gram-negative respiratory pathogens) molecule that is expressed at epithelial sites.
