MRP4 Knockout Caco-2 Cells

The C2BBe1 cells, a subclone of Caco-2 cells, correspond to ATCC CRL-2102. The MRP4 knockout C2BBe1 cells are adenocarcinoma, epithelial cells from a human caucasian male (aged 72 years) with functional knockout of the ABCC4 (MRP4) efflux transporter.

The following posters and articles demonstrate how Caco-2 cells can be used for cell based assays:

Caco-2 Transporter Knockout Cell Based Assays

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 knockout of the MRP4 gene eliminates the reliance on chemical inhibitors to determine if a compound is an MRP4 substrate
• The vial format enables the MRP4 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
