The CellSensor™ GAS-bla ME-180 cell line contains a beta-lactamase reporter gene under control of the Gamma Activated Sequence (GAS) response element stably integrated into ME-180 cells. To construct this cell line, the GAS-bla construct was transduced into ME-180 cells by lentivirus. Flow cytometry was used to isolate cells responsive to Interferon Gamma (IFN-γ). This cell line is validated for DMSO tolerance, cell number, stimulation time, substrate loading time, as well as Z'and EC50 concentrations for IFN-&gamma. The CellSensor™ GAS-bla ME-180 cell line is responsive to IFN-γ and can be used to probe the JAK/STAT signaling pathway. This cell line can be adapted for high-throughput screening of agonist or antagonist compound libraries. Candidate drugs can be tested for dose response against this cell line.
