The Caco-2 subclone C2BBe1 cells are ideal for transporter analysis as they express multiple transporters, are human derived, and grow in a homogenous monolayer that forms tight junctions necessary for efflux ratio analysis. Other benefits include:

• A functional double knockout of the MDR1 gene and BCRP gene eliminates the reliance on chemical inhibitors to determine if a compound is an MRP2 substrate
• The vial format enables the MDR1 and BCRP knockout cells to be included in standard drug transporter protocols
• Human assay with no interference from animal inhibitors
• Overcome the limitations of RNAi and knockdown cell lines that arise from remaining transporter functionality

The C2BBe1 cells, a subclone of Caco-2 cells, correspond to ATCC CRL-2102. The MDR1 and BCRP knockout C2BBe1 cells are adenocarcinoma, epithelial cells from a human caucasian male (aged 72 years) with functional knockout of the ABCB1 and ABCG2 (MDR1/BCRP) efflux transporters.
