Buy CJC-1295 With DAC Research Peptide

CJC-1295 With DAC (Drug Affinity Complex) is a synthetic 30-amino acid analogue of growth hormone-releasing hormone (GHRH). With a molecular weight of 3647.28 g/mol, CJC-1295 DAC (CAS 446262-90-4) features a maleimidopropionyl group conjugated to a C-terminal lysine residue, designed to facilitate bioconjugation with serum albumin. Produced via solid-phase peptide synthesis, CJC-1295 DAC acts at the GHRH receptor (GHRH-R).

CJC-1295 With DAC is investigated in preclinical endocrinology for its extended pharmacokinetic profile relative to unmodified GHRH analogues. The DAC bioconjugation strategy represents a distinct approach to prolonging peptide half-life through albumin binding rather than sequence modification alone, and has been a subject of particular research interest. In vitro studies in rat anterior pituitary somatotroph preparations have examined GHRH-R binding characteristics and downstream cAMP-mediated signalling, characterising the receptor binding kinetics that underpin CJC-1295 DAC’s agonist activity at GHRH-R [1]. Published pharmacokinetic studies in rodent models have investigated sustained receptor engagement and prolonged circulating peptide concentrations following a single administration, with researchers examining albumin-peptide dissociation kinetics and their implications for extended receptor occupancy duration [2].

CJC-1295 With DAC is produced to research-grade standards and independently verified by third-party HPLC and MS-UPLC analysis before dispatch. Vials are vacuum sealed and stored in a temperature controlled, monitored cold storage system. Certificates of Analysis are available on request.
