2-Me PeER
2-Me PeER is a rhodamine dye-based fluorescent probe that detects CYP3A4 activity. In fluorescence-activated cell sorting (FACS) based on CYP3A4 activity, homogeneous and functional human induced pluripotent stem cell (hiPSC)-derived hepatocytes and intestinal epithelial cells can be obtained with the aid of 2-Me PeER.
