PT-141

PT-141 is a synthetic analogue of alpha-melanocyte-stimulating hormone, or alpha-MSH. It belongs to the melanocortin peptide family and is studied for its interaction with melanocortin receptors, including MC3R and MC4R.

Research context

Melanocortin receptors form a family of related signaling proteins. A peptide can interact with more than one member of that family, so receptor identity is an important part of interpreting an experiment. PT-141 research helps examine how an altered peptide structure engages these related targets.

The distinction between receptor binding and activation is useful here: binding concerns the peptide’s interaction with a receptor, while activation concerns the signal produced after that interaction. These questions place PT-141 within receptor pharmacology and peptide structure-activity research.

Structure-activity research on melanocortin peptides compares analogues side by side at shared receptor targets, measuring how sequence and conformation changes alter binding affinity and activation. PT-141 contributes to this work as a structurally distinct analogue whose cyclic character and modified residues give it a defined position in comparative melanocortin pharmacology.

Quality, Purity and Documentation

Review the analytical documentation listed for the selected size. Reports describe the samples identified in them; they do not by themselves confirm that current stock matches those samples. If no matching report is listed, contact Prestige Peptides for documentation before ordering.

Planned format

PT-141 10mg is planned as a lyophilized (freeze-dried) powder in a sealed 10mg vial. Lyophilization removes water under vacuum at low temperature, producing a dry preparation suited to controlled laboratory storage. This listing is pending release; the notification form on this page registers interest for availability updates.

Storage and handling

Store lyophilized vials at -20°C or below, protected from light and moisture. Allow sealed vials to equilibrate to room temperature before opening to limit condensation inside the vial. Once opened, handle with clean laboratory technique, minimize exposure to ambient humidity, reseal promptly, and record the lot number in laboratory documentation for traceability.
