Anti-PMEL Antibody is a potent monoclonal antibody targeting the melanocyte-specific protein PMEL (gp100), acting by specifically binding to the fibrillar matrix formed during melanosome maturation. The compound is an essential tool for investigating melanocyte differentiation, melanosome biogenesis, and pigmentation-related pathological mechanisms, aiming to quantitatively evaluate cellular metabolic and differentiation states by identifying processed, mature PMEL proteins.
