Product Overview
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide analog of the endogenous alpha-melanocyte-stimulating hormone (α-MSH). Developed via targeted structural truncation and cyclization of Melanotan II, PT-141 possesses a distinct neurogenic mechanism of action, operating as a high-affinity agonist at central melanocortin receptors (primarily MC3R and MC4R) within the central nervous system.
In preclinical biomolecular models, PT-141 serves as an essential reference standard to investigate neuroendocrine signaling pathways, copulatory behavior kinetics, and central nervous system-mediated vascular responses. Its unique molecular configuration acts independently of the local vascular system, anchoring it as a vital tool for cellular signaling and in vitro receptor binding assays.

Laboratory Handling & Storage Guidelines
- Reconstitution: Reconstitute using sterile bacteriostatic water or standard analytical saline solutions. Gently swirl the vial in a smooth circular motion; avoid aggressive vortexing to preserve optimal cyclic compound architecture.
- Long-Term Storage: Store the raw lyophilized powder desiccated at -20°C to -80°C. Protect meticulously from moisture contamination, ambient atmospheric humidity, and direct solar exposure.
- Short-Term Stability: Post-reconstitution, the matrix solution must be stored under stable refrigeration at 2°C to 8°C and utilized within 14 days to preserve maximum biochemical integrity.
