Antho-Rfamide CAS NO.107535-01-3
Product Overview
Antho-RFamide is a high-purity, synthetic pentapeptide neuropeptide (pGlu-Gly-Arg-Phe-NH2) originally isolated from marine cnidarians such as the sea anemone Anthopleura elegantissima and the sea pansy Renilla köllikeri, supplied as a lyophilized white powder for advanced neurobiological and evolutionary research.
Structural Motif & ApplicationAs a canonical member of the RFamide family of neuropeptides, it features a signature C-terminal Arg-Phe-NH2 (RFamide) motif and an N-terminal pyroglutamate residue, making it a fundamental tool for scientists studying primitive nervous systems, neuromuscular junctions, and G-protein-coupled receptor (GPCR) signaling.
Its well-defined sequence and potent bioactivity make it an essential reference standard for academic laboratories, marine biology institutes, and pharmaceutical R&D teams focused on neurophysiology, comparative neuroscience, and the exploration of novel GPCR ligands derived from marine organisms.
