NCoA-3 Antibody (E-11) is a mouse monoclonal IgG2a antibody that detects NCoA-3 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). NCoA-3, also known as RAC3, ACTR, AIB-1, and p/CIP, plays a crucial role as a transcriptional coactivator that interacts with steroid hormone receptors, thereby influencing gene expression in response to hormonal signals. NCoA-3 is particularly significant in cancer biology, as NCoA-3 is often overexpressed in estrogen receptor-positive ovarian and breast cancers, contributing to transcriptional activation of p300/CBP-dependent transcription factors. NCoA-3′s ability to modulate transcriptional activity highlights NCoA-3′s importance in cellular processes such as proliferation and differentiation, making NCoA-3 a valuable target for research into hormone-related cancers and potential therapeutic interventions. Anti-NCoA-3 antibody (E-11) provides a reliable tool for studying NCoA-3 dynamics and interactions within the cellular environment, facilitating advancements in understanding hormone signaling pathways and their implications in disease.

When should the TransCruz reagent sc-166751 X be used instead of the standard form sc-166751?

Asked by: Cweed
Thank you for your question. We recommend using the TransCruz reagent form when performing ChIP or GelShift assays. This form can also be used in other applications such as Western Blot or IHC, but the dilution should be adjusted by a factor of 10 to account for the higher original concentration.
