Melanotan II is a synthetic analog of the alpha-melanocyte-stimulating hormone (α-MSH), originally developed for laboratory investigation into melanin regulation, pigmentation response, and melanocortin receptor pathways. It remains a key reference peptide in pigmentation and cellular signaling research models.

Key Research Highlights

• Used in receptor-binding and pigmentation studies focused on MC1R and MC4R activity.
• Explored in vitro for melanin synthesis signaling and receptor-mediated energy regulation.
• Frequently employed as a comparative analog in melanocortin-pathway modeling.

Overview

Melanotan II belongs to the family of cyclic lactam analogs of α-MSH. Research applications often focus on quantifying its receptor affinity and measuring downstream effects on melanogenesis, cell signaling, and peptide stability under controlled laboratory conditions.

Analytical & Handling Information

• Form: Lyophilized peptide powder
• Strength: 10 mg per vial
• Included: 1 × 1.2 ml sterile bacteriostatic water for laboratory reconstitution
• Reconstitution: Add water slowly along the vial wall and swirl gently until dissolved (do not shake)
• Storage: Store refrigerated at 2–8 °C once reconstituted; protect from light

Reference Concentration & Sampling Context

Published in-vitro studies examining Melanotan II commonly reference concentration ranges between 0.1 µM – 10 µM. These parameters are utilized for receptor-binding and pigmentation models to evaluate activity at different exposure levels. Observation periods vary by experimental design and measured endpoints.

Reference Frequency Table

The following table summarizes observation frequencies and sampling intervals reported in published laboratory research. These are not dosage recommendations but reflect standard measurement schedules for repeat-sampling peptide stability or receptor activity studies.

These intervals are representative of controlled in-vitro sampling used to monitor peptide performance, receptor activity, and time-dependent changes. They are provided solely for research-reference and reproducibility purposes.
