Endocrine Peptides

Endocrine catalog peptides are hormone fragments and releasing-factor sequences used in receptor pharmacology. They are research reagents for in-vitro or institutionally approved animal protocols, not medicines. Confirm pyroglutamate, amidation and disulfide pairing on the product page; those features change both molecular weight and biological readout in a binding assay. GnRH, TRH, oxytocin, vasopressin, somatostatin-14, secretin and ACTH fragments are examples of names that appear in this group. Several of those sequences also sit near cardiovascular or neuropeptide lists; the category is a browsing aid, not a pharmacological classification you should cite. If you need a stable analogue, a fluorescent tracer or a truncated receptor ligand, request custom peptide synthesis with the published residue string attached. Purity on a catalog page is the HPLC grade of that listing; a tighter grade is a custom remake. Storage and reconstitution follow the general peptide handling notes. Nothing in this category is offered for clinical use.

If the analogue you need is not listed, request custom peptide synthesis with the exact sequence and purity.
