CJC-1295 With DAC

Contents DAC:GRF Form / storage Lyophilized powder; store at −20 °C, protect from light Purity ≥98% — see lot COA CAS No reliably distinct CAS for the DAC conjugate (confirm before publishing); identify by PubChem CID 91971820 Molecular formula C165H269N47O46 Molecular weight ~3647 g/mol Sizes 5 mg Testing Identity (UV/Vis λmax), purity, assay (Beer-Lambert), heavy metals, microbial (TAMC/TYMC) COA Batch-specific — view on this page Research background CJC-1295 with DAC is a tetra-substituted GHRH(1-29) analog that additionally bears a maleimidopropionyl DAC linker at a C-terminal lysine; in research settings the linker reacts with a cysteine on circulating albumin to form a covalent adduct, a design studied for greatly extending circulating half-life. The four substitutions are investigated for resisting DPP-IV cleavage and improving stability. The albumin-binding strategy is of interest in pharmacokinetics research on sustained GHRH-receptor engagement and the resulting GH/IGF-1 axis dynamics in preclinical models. Spec note (important): Many vendors mislabel the DAC version with CAS 863288-34-0 / C152H252N44O42 — those values actually belong to the without-DAC peptide below. The DAC conjugate is C165H269N47O46, ~3647 g/mol.
