Melanotan I (Melanotan-1) is a synthetic analogue of alpha-melanocyte-stimulating hormone (alpha-MSH) studied in melanocortin receptor research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. Melanotan I is investigated in research on melanocortin receptor signaling, pigmentation pathways and related cellular mechanisms, and is commonly applied in cell-based and preclinical studies. The freeze-dried format ensures high stability and easy reconstitution for reproducible experimental dosing. Strict quality control is maintained on every batch, and COA is available for specific batches on request. Keep the unopened product sealed at 2-8 degree C away from light; -20 degree C is recommended for long-term storage. Small and bulk orders are both welcome, and OEM and discreet neutral packing are offered. The linear alpha-melanocyte-stimulating-hormone analog is engineered for extended melanocortin-1 receptor activation, and studies cover pigmentation pathways and photoprotection mechanisms. Its stability supports prolonged exposure protocols. The product is provided lyophilized with batch purity data. The analog is often used in dose-response studies of melanocortin-1 receptor signaling, with endpoints including pigment production and receptor internalization. Its linear architecture simplifies structure-activity comparisons, and the lyophilized product with purity data supports reproducible in vitro and in vivo work. The lyophilized format provides excellent stability and simplifies reconstitution for reproducible dosing.
