Cayman's MC3R Reporter Assay consists of a 96-well plate coated with a transfection complex containing DNA constructs for MC3R and a cAMP response element regulated Secreted Alkaline Phosphatase (SEAP) reporter (MC3R Reverse Transfection Strip Plate). Cells grown on the transfection complex will express MC3R at the cell surface. Binding of agonists to MC3R initiates a signal transduction resulting in expression of SEAP. SEAP activity is measured following addition of luminescence-based alkaline phosphatase substrate provided in the kit.
