Neuropeptides Peptides

Neuropeptide catalog items on this site are short signaling peptides that laboratories use as receptor ligands, assay standards or starting points for analogue design. The listings are research materials. Sequences follow the classical published forms; CAS numbers are given only when they identify that form. A truncated, labeled or cyclized analogue that is not stocked should be requested as custom peptide synthesis rather than treated as a missing SKU. Typical entries in this group include substance P, neuropeptide Y, neurotensin, CGRP and related ligands that appear in receptor-binding and signaling protocols. Confirm C-terminal amidation, pyroglutamate and disulfide pairing on the product page before you treat the name as sufficient. Those features change both molecular weight and the biological readout in a binding assay. Catalog supply does not replace a custom lot when you need a biotin handle, a fluorescent dye or a truncated fragment that is not listed. Related technical notes on sequence design live in the custom peptide synthesis guide. Storage remains the same as for other lyophilized research peptides: keep the vial dry and cold, and reconstitute a small aliquot first. These items are not medicines and are not supplied for administration to humans.

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