KEY HIGHLIGHTS

EXPLORE PT-141

Rigorous Quality Testing

Each batch of PT-141 undergoes multiple layers of analytical verification to ensure consistent lab performance. Peptide purity is confirmed at ≥99% via high-performance liquid chromatography (HPLC), while peptide sequence integrity is validated through tandem mass spectrometry (MS/MS). Endotoxin levels are certified below 0.1 EU/mg to prevent assay interference, and thermal stability is assessed by Fourier-transform infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC). These quality controls guarantee that every vial delivers reliable, research-grade peptide for sensitive protocol applications.

Why Choose PT-141?

PT-141 stands out in peptide research for its high selectivity toward melanocortin-4 receptors, enabling precise investigation of neuromodulatory pathways without cross-reactivity in erythropoietic or metabolic receptor systems. Its well-documented use in rodent and non-human primate models provides a robust evidence base for experimental design. Each PT-141 lot is accompanied by a Certificate of Analysis (COA), offering full traceability from synthesis through batch release. Manufactured in ISO-certified U.S. facilities under cGMP-like conditions, PT-141 ensures consistency and compliance for all your laboratory needs.

What Sets PT-141 Apart

Unlike broader-acting melanocortin peptides, PT-141 delivers targeted activation of central melanocortin-4 receptors, making it uniquely suited for research into sexual arousal circuitry and vascular function. Its molecular design avoids off-target effects on red blood cell production and systemic metabolism, allowing clear interpretation of neuromodulatory and endothelial endpoints. Coupled with its demonstrated stability in both lyophilized and reconstituted forms, PT-141 offers researchers unparalleled confidence in long-term study reproducibility and data integrity.
