Alpha-melanocyte-stimulating hormone is a tridecapeptide derived from proopiomelanocortin that acts at melanocortin receptors to regulate pigmentation, melanocortin signaling and anti-inflammatory responses. Investigators use the native sequence as the reference agonist in MC1 and MC3-MC5 receptor studies, and its defined structure supports dose-response and structure-activity comparisons. In melanocortin research, this tridecapeptide is usually the reference agonist for MC1 and MC3-MC5 receptor assays, and investigators measure receptor activation, pigment endpoints and anti-inflammatory readouts in parallel. Dose-response arms are typical, and the lyophilized material is prepared fresh per treatment. Our records verify purity, and matched lots are available for structure-activity comparisons, with delivery arranged within recommended conditions. For this tridecapeptide, the standard arrangement is matched lots with the analysis record included, supporting structure-activity comparisons across melanocortin subtypes. The lyophilized material keeps well under the indicated storage conditions, and our notes cover both powder and solution. Trial and bulk quantities are available. Orders are processed promptly after confirmation, with professional packaging that protects lyophilized material during transit. We support both trial quantities for evaluation and bulk volumes for ongoing research programs, with dedicated after-sales assistance at every step.
