Peptide Fragments and Analogues of Endogenous Proteins

Each compound here is a short synthetic sequence taken from, or modeled on, a longer endogenous peptide or protein. Semax is ACTH(4–7) extended with a Pro-Gly-Pro C-terminal cap. Selank is the tetrapeptide tuftsin with the same Pro-Gly-Pro extension. DSIP is a nine-residue peptide, about 849 Da. AOD-9604 is the C-terminal fragment Tyr-hGH(177–191) containing a single disulfide loop. ARA-290 (cibinetide) is an 11-residue peptide derived from helix B of erythropoietin.

GHK-Cu is the tripeptide Gly-His-Lys complexed with copper(II); its characterization is coordination chemistry rather than receptor pharmacology. IGF-1 LR3 is an 83-residue recombinant protein, an Arg3-substituted analogue of IGF-1 with a 13-residue N-terminal extension, and is the one product in this group that is not a synthetic peptide.

Every compound we supply is independently tested for purity and identity, with certificates published on the product page as testing is completed. For Research Use Only.
