Early screening of a drug candidate’s potential to induce or inhibit CYP1A1/2 is a critical step in the drug development process. Cayman's CYP1A1/2 Induction Reporter Assay Kit is a novel method to assess CYP1A2 induction. Our Reverse Transfection Reporter Assays have overcome many of the disadvantages of other transfection approaches. Cayman's CYP1A1/2 Induction Reporter Assay Kit consists of a 96-well plate coated with a transfection complex containing a Secreted Alkaline Phosphatase (SEAP) reporter construct regulated by the human CYP1A1/2 gene promoter. Cells grown on the CYP1A1/2 Reverse Transfection Strip Plate will introduce the reporter gene into the nucleus. Binding of inducer-activated endogenous transcription factors to the CYP1A1/2 promoter initiates a signal resulting in expression of SEAP which is secreted into the cell culture medium. Aliquots of medium are removed at time intervals beginning at about 24 hours.
