Description

PT-141 10 mg

Buy PT-141 10 mg for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial.

PT-141, known as bremelanotide in the research literature, is a synthetic cyclic peptide studied at melanocortin receptors.

Identify the ligand and presentation

PT-141 and Melanotan II have related cyclic structures but different terminal chemistry. Melanotan I is a separate linear analog. Use the exact ligand specified by the experiment rather than treating these names as interchangeable.

For material matching, check the sequence, ring linkage, terminal groups and supplied chemical form. A matching catalog name alone does not confirm equivalence to a reference standard or a finished pharmaceutical formulation.

Receptor binding and signaling research

A 2021 structural study examined bremelanotide bound to the melanocortin-4 receptor (MC4R) and its G protein. Cryo-electron microscopy mapped molecular contacts, while experiments in transfected cells measured cAMP signaling after changes to receptor residues.

The combination connects a structural observation with a functional measurement. It does not mean that binding and signaling are the same endpoint, or that an MC4R experiment proves selectivity across every melanocortin receptor. The tested system also does not establish a clinical outcome or certify the activity of this product’s lot.

Review the COA and product files

COA & Documents contains the available batch reports and product records. Match the certificate of analysis to the item and lot, and distinguish identity testing, chromatographic purity and measured content. Use the methods and results actually shown in the report.

The powder amount is not a concentration, and vial capacity does not determine an experimental preparation. Confirm solvent compatibility and handling or storage requirements for the supplied form and laboratory method. Information for a nasal formulation or other finished product should not be used as instructions for this material.
