AsPC-1/STAT3 Reporter (Luc) cells are derived from the human pancreas adenocarcinoma AsPC-1 cell line by stably integration of a STAT3 firefly luciferase reporter construct. AsPC-1 cell line has been widely used in cancer research and drug development. AsPC-1/STAT3 Reporter (Luc) cells stably express firefly luciferase under the control of the STAT3 response elements, can be used for monitoring the activity of STAT3 signaling pathway.
