Research Overview

PT-141 peptide​ Overview

PT-141 is a synthetic melanocortin receptor agonist derived from the analog Melanotan II. It primarily activates the MC3R and MC4R subtypes of the melanocortin receptor family, making it a valuable compound in studies of neuropeptide signaling, central nervous system modulation, and GPCR-targeted pharmacology. PT-141 is widely utilized in preclinical research to evaluate neuroendocrine function, sexual behavior pathways, and receptor selectivity.

This 10mg formulation is research-grade and prepared under stringent quality control conditions for laboratory use. It supports studies examining ligand–receptor dynamics, signaling cascade activation, and melanocortin-linked cellular responses.

  • Structure: Synthetic cyclic heptapeptide related to Melanotan II
  • Receptor Targeting: MC3R, MC4R (primary), with documented MC1R activity
  • Primary Applications: GPCR activation, CNS signaling, inflammation modulation, pigmentation pathways
  • Mechanism of Action: Triggers cAMP and ERK pathways via G-protein-coupled receptor binding
  • Purity & Form: Lyophilized peptide, ≥99% HPLC-verified purity
Storage & Handling

PT-141 peptide​ Storage & Handling

All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.

  • On arrival: Store vials in a cool, dry place away from heat and direct sunlight.
  • Long-term (powder): For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
  • After reconstitution: Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.

Note: Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.

FAQ
