Sequence: Tyr-D-Ala-Asp-Ala-Ile-Phe-Thr-Gln-Ser-Tyr-Arg-Lys-Val-Leu-Ala-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Leu-Ser-Arg-NH2
Chemical Description
CJC-1295 No DAC (also known as Modified GRF 1-29) is a synthetic, tetrasubstituted analogue of the endogenous peptide GHRH(1-29). The structural modifications involve specific amino acid substitutions designed to increase resistance to cleavage by the enzyme Dipeptidyl Peptidase-4 (DPP-IV). Unlike the "DAC" variant, this peptide lacks the Drug Affinity Complex moiety, resulting in a kinetic profile that allows for the study of rapid receptor activation and clearance mechanisms in vitro.
Research Applications
This compound is strictly for laboratory research use in the study of:
- Pulsatile Receptor Signaling: Research into the non-continuous activation of the GHRH receptor on anterior pituitary cells.
- Enzymatic Stability Assays: Comparative analysis of peptide degradation rates in the presence of plasma proteases versus native GHRH.
- Somatotroph Kinetics: In vitro measurement of cyclic AMP (cAMP) accumulation and downstream signal transduction in somatotroph cultures.
