PT-141 Liquid Spray — Atomized Research Solution
Technical Overview
This listing supplies PT-141 (bremelanotide), a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone, prepared as a ready-to-dispense atomized solution. Each 10 mL metered spray bottle contains 10 mg PT-141 in a proprietary carrier/base solution at 1 mg/mL, delivering 100 mcg per metered spray. Supplied pre-dissolved: no reconstitution step, no diluent, no syringe.
Research Context
PT-141 is a cyclic heptapeptide featuring a side-chain lactam bridge between Asp and Lys, N-terminal acetylation, and norleucine and D-phenylalanine substitutions that confer protease resistance. It is studied as a non-selective melanocortin receptor agonist with preferential activity at MC3R and MC4R, and is used as a stable reference compound in receptor-binding work, downstream cAMP signalling assays, and receptor-selectivity comparisons against alpha-MSH and NDP-MSH. The spray format serves laboratory work that calls for a stable, metered liquid preparation rather than a lyophilized vial.
