MRP7 Knockout Caco-2 Cells

The C2BBe1 cells, a subclone of Caco-2 cells, correspond to ATCC Cat. No. CRL-2102. The MRP7 knockout C2BBe1 cells are adenocarcinoma, epithelial cells from a human caucasian male (aged 72 years) with functional knockout of the MRP7 efflux transporter.

The three week production lead time begins on the Monday following a purchase, in the third week the cells are shipped overnight for receipt on Tuesday or Wednesday. As a biologic product that′s shipped at room temperature the cells must be processed immediately upon receipt.

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 juntions which is necessary for efflux ratio analysis. Other benefits include:

- A functional knockout of the MRP7 gene eliminates the reliance on chemical inhibitors to determine if a compound is an MRP7 substrate
- The 24 well Transwell format enables the MRP7 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
