PT-141 is a laboratory-synthesized peptide sequence derived from melanocortin receptor research literature. It has gained attention in scientific environments due to its defined molecular structure and its role in experimental studies exploring receptor-binding mechanisms and intracellular signaling pathways.
This product is supplied as a multi-vial kit to support structured research protocols requiring consistency across experimental replicates.
Product Description
PT-141 is a cyclic heptapeptide fragment referenced in preclinical and laboratory studies focused on melanocortin receptor interactions within controlled models. Because of its distinct amino acid sequence, it is commonly selected for experimental designs examining peptide-driven receptor activation and downstream signaling mechanisms.
West Peptides provides PT-141 in lyophilized form to preserve structural integrity and allow for controlled preparation using appropriate sterile solvents in laboratory settings.
Each kit contains ten vials, enabling researchers to maintain uniformity across study phases or repeated analytical procedures.
Kit Details

This multi-vial configuration is intended to support repeatability and structured research workflows.
Research Context
In laboratory investigations, PT-141 has been referenced in studies examining melanocortin receptor subtypes and peptide-mediated signaling interactions. Defined cyclic peptide fragments such as PT-141 are often used to explore how specific molecular sequences behave within controlled experimental environments.
Because melanocortin-derived peptide sequences represent an active area of receptor pharmacology research, PT-141 is frequently incorporated into exploratory and comparative study models.
Handling and Preparation
PT-141 is supplied in freeze-dried format to maintain stability during storage. Reconstitution should be performed using appropriate sterile laboratory solvents and handled by qualified personnel within controlled research environments.
Proper storage conditions help maintain consistency and analytical reliability throughout experimental use.
