**Background of ZFP42 Antibody**
The ZFP42 antibody targets the ZFP42 protein, also known as Zinc Finger Protein 42 or REX1 (Reduced Expression Protein 1), encoded by the *ZFP42* gene in humans. ZFP42/REX1 is a transcription factor containing tandem Cys2-His2 zinc finger domains, primarily recognized for its role in maintaining pluripotency in embryonic stem cells (ESCs). It is a downstream target of core pluripotency regulators like OCT4. SOX2. and NANOG, and its expression is tightly associated with the undifferentiated state of ESCs. During early embryonic development, ZFP42 is highly expressed in the inner cell mass of blastocysts but is downregulated upon differentiation, making it a key marker for pluripotency.
ZFP42 antibodies are widely used in stem cell research to identify and characterize pluripotent cells via techniques such as immunocytochemistry, Western blotting, and flow cytometry. These antibodies help assess the quality of induced pluripotent stem cells (iPSCs) or ESCs by confirming the presence of ZFP42 protein, which correlates with their undifferentiated status. Additionally, ZFP42 has been implicated in regulating genomic imprinting and telomere maintenance, with aberrant expression linked to certain cancers and developmental disorders.
Commercial ZFP42 antibodies are typically validated for specificity using knockout cell lines or siRNA-mediated knockdown to ensure minimal cross-reactivity. Their application extends to developmental biology, regenerative medicine, and disease modeling, underscoring their importance in understanding cellular reprogramming and lineage commitment.
