Corning® Gentest™ ATPase Assay Kit Colorimetric Reagent Kit for ABC Transporter Membrane ATPase Assays The Corning Gentest ATPase Assay Kit is a flexible, complete reagent kit delivering consistency across lots for testing all Corning human and animal ABC transporter membranes with one simple protocol. The assay kit complies with industry guidance recommendations. Features w Supports FDA-recommended P-gp and BCRP, as well as MRP membrane panels w Provides a simple, single protocol that accommodates all human and animal ABC transporter membrane studies w Delivers maximum flexibility allowing researchers the ability to perform a single transporter study or a full complement of P-gp, MRP, and BCRP studies with one kit w Saves researchers time by eliminating reagent preparation steps; assays can be completed within one day w Provides flexibility with single aliquot color reagents and stability for up to eight freeze-thaw cycles Kit supports industry guidance recommendations for ABC transporters The kit supports USFDA-recommended1 P-gp and ITC recommended BCRP2 in vitro studies. The kit includes verapamil and sulfasalazine to determine if a new chemical entity (NCE) is a substrate or inhibitor of P-gp or BCRP, respectively. Provides a high degree of reagent lot-to-lot consistency Three ATPase kit lots were evaluated for lot-to-lot consistency using the same hP-gp, hBCRP, and hMRP2 membrane lots and the results obtained demonstrated reproducibility within experimental uncertainty (see Figure 1/Table 1). Flexible format with one kit, one protocol for all human and animal transporter membranes Designed for maximum flexibility and researcher convenience, one ATPase protocol accommodates human and animal P-gp, MRP, and BCRP studies. Multiple transporter-use format supports single transporter assays such as five P-gp assays, or any combination of P-gp, MRP, and BCRP assays. Robust design supports multiple time usage Single reagent aliquots allow researchers to use one plate at a time (supports five 96 well plate assays), while saving the remaining reagents for use at a later date. The robust kit design supports up to eight freeze-thaw cycles with no significant loss in activity (see Figure 2). 1 USFDA/CDER, Drug Interaction Studies - Study Design, Data Analysis, and Implications for Dosing and Labeling, DRAFT GUIDANCE, September 2006.
