The GeneBLAzer™ CMV-bla Jurkat Cell Line constitutively expresses beta-lactamase under the control of the CMV promoter in Jurkat cells. A stable population was obtained using 1 mg/ml Geneticin™ (G418) selection followed by isolation of a clone by fluorescence-activated cell sorting (FACS).

CMV-bla Jurkat cells can be used as a positive control for beta-lactamase expression experiments. When the cells are loaded with CCF2-AM or CCF4-AM substrate and excited with 409 nm light, the cells will fluoresce blue.
