THP-1/IFN beta reporter (GFP) cells are derived from the human monocytic THP-1 cell line by stably integration of a IFN beta GFP reporter construct. The THP-1 cell line is widely used to study the function of monocytes and macrophages, as well as in leukemia research. THP-1/IFN beta reporter (GFP) cells express eGFP under the control of the INF beta promoter, can be used for in vitro assays and in vivo imaging.
