GeneBLAzer® ADORA2B-CRE-bla CHO-K1 cells contain the human Adenosine A2B Receptor (ADORA2B), (Accession # NM_000676) stably integrated into the CellSensor® CRE-bla CHO-K1 cell line. CellSensor® CRE-bla CHO-K1 cells (Cat. no. K1535) contain a beta-lactamase reporter gene under control of the CRE. The GeneBLAzer® ADORA2B-CRE-bla CHO-K1 cells are functionally validated for Z’-factor and EC50 concentrations of 5’-(N-Ethylcarboxamido)adenosine. In addition, ADORA2B-CRE-bla CHO-K1 cells have been tested for assay performance under variable conditions.
