ZFP42 antibody targets the ZFP42 protein, commonly known as REX1 (Reduced Expression Protein 1), a transcription factor encoded by the *ZFP42* gene located on human chromosome 4. REX1 is a member of the KRAB-zinc finger protein (KRAB-ZFP) family and plays a critical role in maintaining pluripotency in embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). It acts as a downstream effector of core pluripotency regulators like OCT4. SOX2. and NANOG, and its expression is tightly associated with the undifferentiated state of stem cells.
ZFP42 antibodies are widely used in stem cell research to identify and characterize pluripotent cells, monitor differentiation status, and study reprogramming mechanisms. These antibodies are employed in techniques such as Western blotting, immunofluorescence, and flow cytometry to detect REX1 protein levels, which decline as cells differentiate. REX1 is also implicated in regulating genomic stability, imprinting, and early embryonic development.
Notably, ZFP42 antibodies help investigate the protein's role in diseases, including cancer, where aberrant REX1 expression has been observed. Research using these antibodies has contributed to understanding pluripotency networks and developing regenerative therapies. However, specificity validation is essential due to potential cross-reactivity with other zinc finger proteins. Overall, ZFP42 antibodies are vital tools for exploring stem cell biology and epigenetic regulation.
