Description

Ipamorelin is a synthetic pentapeptide with the sequence Aib-His-D-2-Nal-D-Phe-Lys-NH₂, molecular formula C₃₈H₄₉N₉O₅, a molecular weight of approximately 711.85 Da, and CAS number 170851-70-4. Among GHS-R1a-binding peptides studied in research models, Ipamorelin is distinguished by its high binding selectivity for GHS-R1a and minimal cortisol (via ACTH), prolactin, or aldosterone release in cellular assays.

In laboratory research, Ipamorelin is utilized in selective GHS-R1a binding studies, GHS-R1a signal-transduction mechanism investigations, somatotroph cell signaling-specificity characterization, comparative receptor-binding studies with ghrelin and other GHS-R1a-binding research peptides, calcium-mobilization assays, and cAMP accumulation experiments.

Supplied as a lyophilized powder with ≥99% purity verified by HPLC. For storage and handling conditions, refer to the Certificate of Analysis provided with each lot. This product is intended strictly for laboratory research use only (RUO) and is not for human consumption, therapeutic use, or any diagnostic purposes.
