This shelf holds the analogs characterized against the growth-hormone-releasing-hormone receptor (GHRHR) and the growth-hormone secretagogue receptor (GHS-R1a, the ghrelin receptor). Every item is supplied lyophilized as a laboratory reference material and verified by reverse-phase HPLC.
The compounds differ mainly in half-life and receptor selectivity, which is usually what determines which one suits an assay. Sermorelin is the truncated GHRH(1-29) sequence and is short-acting. CJC-1295 without DAC carries the tetrasubstituted backbone that resists DPP-4 cleavage; the DAC variant adds a maleimido linker that conjugates to serum albumin, extending measurable half-life from minutes to days, which is why the two are not interchangeable in a time-course experiment. Tesamorelin is a stabilized GHRH analog with a trans-3-hexenoyl group at the N-terminus. On the secretagogue side, ipamorelin is a selective pentapeptide with minimal cross-activity at other receptors, while hexarelin is a hexapeptide GHRP with documented CD36 binding alongside GHS-R1a.
When choosing, compare receptor target, net peptide content per vial, counter-ion form and the stated purity method against your assay design. All items are for in-vitro laboratory research use only.
