The CellSensor® c-fos-bla ME-180 cell line contains a beta-lactamase reporter gene under control of the c-fos response element stably integrated into ME-180 cells. To construct this cell line, the c-fos-bla construct was transduced into ME-180 cells by lentivirus. Flow cytometry was used to isolate cells responsive to epidermal growth factor (EGF). This cell line is validated for DMSO tolerance, cell number, stimulation time, substrate loading time, as well as Z' and EC50 concentrations for EGF. The CellSensor® c-fos-bla ME-180 cell line is responsive to EGF, HGF, IL-6, OSM, TNFα, IL-1-alpha; and PMA/Thaps, and can be used to probe the JNK/P38/MAPK and JAK/STAT signaling pathways. This cell line can be adapted for high-throughput screening of agonist or antagonist compound libraries. Candidate drugs can also be tested for dose response against this cell line.
