The MC1R polyclonal antibody is produced by the immune system of a rabbit against the recombinant human MC1R protein (1-37aa). This MC1R antibody targets the human MC1R protein. Its purity is at least 95% using protein G purification. Multiple applications including ELISA, WB, IHC, and IF have been used to validate the specificity and reliability of this MC1R antibody.
The MC1R protein mainly functions to regulate the production of the pigment melanin in melanocytes. Melanin is responsible for giving color to the skin, hair, and eyes and also helps to protect the skin from the harmful effects of UV radiation. Mutations in the MC1R gene can affect the function of MC1R protein and thus alter the generation of melanin, leading to differences in skin, hair, and eye color, as well as differences in the ability to tan and the risk of developing skin cancer.

Receptor for MSH (alpha, beta and gamma) and ACTH. The activity of this receptor is mediated by G proteins which activate adenylate cyclase. Mediates melanogenesis, the production of eumelanin (black/brown) and phaeomelanin (red/yellow), via regulation of cAMP signaling in melanocytes.
