CellSensor™ CRE-bla FreeStyle™ 293F Cell Line

The CellSensor™ CRE-bla FreeStyle™ 293F cell line contains a beta-lactamase reporter gene under control of the CRE response element stably integrated into FreeStyle™ 293F cells. To construct this cell line, the CRE -bla construct was transduced into FreeStyle™ 293F cells by lentivirus. Flow cytometry was used to isolate cells responsive to forskolin. Assay development experiments performed on this cell line included DMSO tolerance, cell number, stimulation time and substrate loading time. Functional validation of this cell line under optimized conditions included and Z' and EC50 determinations using forskolin as a primary agonist. The CellSensor™ CRE-bla FreeStyle™ 293F cell line is responsive to forskolin and can be used to build specific G-protein coupled receptor (GPCR) assays after transfection of additional genes of interest or to detect changes in cellular cAMP levels. This cell line can be adapted for high-throughput screening for agonists or antagonists with compound libraries. Candidate drugs can be tested for dose response against this cell line.
