Why laboratories choose pens and cartridges
A contained 3ml presentation supports clear product identification, consistent format comparison and documented repeat procurement. Compatible refill cartridges also allow an organisation to retain its reusable pen hardware while ordering the required prepared research presentation separately.
This item is prepared only after ordering to minimise elapsed time in the prepared state before dispatch. Refrigerate at 2-8 C and protect from light on receipt. Stability is compound-, preparation- and storage-dependent, so retain and follow the supplied product and batch documentation.

Description and research context
PT-141, also known as bremelanotide, is a synthetic cyclic peptide in the melanocortin analogue family. Its constrained structure provides a defined reference ligand for studying melanocortin-receptor recognition and receptor-subtype selectivity.
Receptor and clinical pharmacology literature identifies agonist activity at MC3R and MC4R. Laboratory systems use this profile to examine melanocortin-receptor binding, G-protein-coupled signalling and comparative pharmacology. Responses vary by receptor expression, concentration and experimental model.
Applications in research
- MC3R and MC4R receptor-binding and activation assays
- Melanocortin receptor-selectivity and cAMP-signalling comparisons
- Structure-activity studies of constrained cyclic melanocortin analogues
Precautions and interpretation
For controlled laboratory research only. Not for human or veterinary use. The cited findings come from specific biochemical, cellular, structural or preclinical models and must not be treated as usage guidance or evidence of a defined outcome outside those models.
