PT-141

Technical Overview PT-141 (bremelanotide) is a cyclic heptapeptide melanocortin analog derived from the alpha-MSH sequence. In biochemical research settings, this peptide is frequently investigated for its role in melanocortin receptor binding and receptor-subtype selectivity studies in vitro. PT-141 is synthesized and purified to research-use analytical standards suitable for controlled laboratory investigation. This material is prepared using established synthesis and purification methods, with purity assessed by HPLC to a level suitable for research and assay use. Its lyophilized (freeze-dried) powder in a sealed research vial format supports stable handling, storage, and preparation in controlled scientific environments.
