**Background of Phospho-Nanog(S285) Antibody**
Nanog is a critical transcription factor essential for maintaining pluripotency in embryonic stem cells (ESCs) and primordial germ cells. Its activity is tightly regulated by post-translational modifications, including phosphorylation, which modulates its stability, subcellular localization, and functional interactions. The phosphorylation of Nanog at serine 285 (S285) has been implicated in regulating its protein turnover and pluripotency-related signaling.
Studies suggest that phosphorylation at S285. mediated by kinases such as GSK3β, promotes Nanog degradation via the ubiquitin-proteasome system, linking this modification to the exit from pluripotency during differentiation. The Phospho-Nanog(S285) antibody specifically detects this phosphorylated form, enabling researchers to study dynamic changes in Nanog activity during stem cell self-renewal, reprogramming, or lineage commitment.
This antibody is widely used in techniques like Western blotting, immunofluorescence, and immunoprecipitation to investigate regulatory mechanisms in ESC biology, cancer stem cells, and induced pluripotency. Cross-reactivity with mouse and human Nanog makes it applicable across model systems. Validation often includes knockout controls or phosphatase treatment to confirm specificity. Understanding S285 phosphorylation provides insights into how pluripotency networks are dynamically controlled, with implications for regenerative medicine and disease modeling.
