PT 141 10mg

PT-141 (Bremelanotide)

PT-141 (bremelanotide) is a cyclic melanocortin-receptor research peptide derived from the α-MSH family. Laboratories use it to investigate melanocortin signalling, receptor selectivity, and downstream second-messenger pathways in vitro under controlled, non-clinical conditions.
For laboratory research only. Not for human use.

• Supplied as a lyophilised solid for stability and straightforward storage.
• Unit size: 10 mg per vial.
• Every batch released only after stringent quality checks.

Handling & storage

1. Storage (dry): Protected from light and moisture.
2. Reconstitution: Bring vial and diluent to room temperature. Reconstitute with
   Bacteriostatic Water 10 ml. Swirl gently—do not vortex.
3. After reconstitution: Store at 2–8 °C, protect from light, use aliquots to reduce handling, and avoid repeated temperature cycling.
4. Compatibility: Use only within research protocols that follow your lab’s SOPs and local regulations.

About PT-141 in research

PT-141 belongs to the melanocortin peptide family used to probe receptor signalling in model systems. Researchers examine receptor engagement, G-protein/second-messenger responses, and structure–activity relationships across melanocortin subtypes in cell-based assays. These investigations occur exclusively in controlled, non-clinical in-vitro environments.

Synthesis & quality

Manufactured via controlled, validated peptide-synthesis processes to deliver high purity and lot-to-lot consistency. Each batch undergoes identity, purity, and appearance checks before release.
