ZFP42 Antibody / Rex1, 100 ug

Rex1 is a protein that in humans is encoded by the ZFP42 gene. It is mapped to 4q35.2. Rex1 (Zfp-42) is a known marker of pluripotency, and is usually found in undifferentiated embryonic stem cells. In addition to being a marker for pluripotency, its regulation is also critical in maintaining a pluripotent state. As the cells begin to differentiate, Rex1 is severely and abruptly downregulated.
