Peptides & Amino Acids

This peptide is derived from the C-terminus of the chemokine, complement fragment 5 anaphylatoxin (C5a). This peptide functions as a C5a receptor agonist. C5a is a plasma protein involved in cellular inflammatory processes by inducing chemotaxis, degranulation of leukocytes, increased vascular permeability, and cytokine production. The cyclohexylalanine at position 5 is crucial to agonist function. Arg at the last position is of the d-isomer.

This heparin-binding peptide is derived from vitronectin (367-378). Vitronectin is a glycoprotein found in monomer form in the blood and oligomer form in the extraceullular matrix. This peptide has been shown to promote the adhesion and undifferentiated growth of human pluripotent stem cells.

Tubulin protein has been purified from porcine brain by an adaptation of the method of Shelanski et al. (1), Further purification to >99% purity was achieved by cation exchange chromatography. Tubulin is supplied as a white lyophilized powder. Fully active for polymerization, this product is lyophilized with a patented technology for increased stability and longevity. T240 is stable for 1 year at 4°C desiccated.

Q-VD-(OMe)-Ph is a second-generation capase inhibitor that is highly potent, brain and cell permeable, irreversible and nontoxic. Q-VD-(OMe)-Ph can inhibit caspase-3 ( IC50=25 nm), caspase-1 (IC50=50 nM), caspase-8 (IC50=100 nM) and caspase-9 (IC50=430 nM).
