CJC-1295 With DAC (Drug Affinity Complex) is a synthetic tetra-substituted peptide analog of growth hormone-releasing hormone (GHRH 1-29) engineered with a C-terminal lysine derivative bearing an N-ε-(3-maleimidopropionyl) group. This maleimide moiety is designed to selectively and covalently bond to free thiol groups on serum albumin (specifically Cys34) in biochemical assays. It is supplied strictly for in vitro covalent bioconjugation kinetics, albumin-binding dynamics, GHRH receptor (GHRHR) activation assays, and laboratory comparative peptide half-life and enzymatic stability models. Supplied as a stable lyophilized powder suitable for analytical reconstitution.
