p-Stat4 Antibody (E-2) is a mouse monoclonal IgG1 kappa light chain antibody that detects Ser 721 phosphorylated Stat4 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). p-Stat4 (E-2) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Stat4 plays a crucial role in the immune response, particularly in mediating signals from interleukin-12 (IL-12), which is essential for the differentiation of T helper 1 (Th1) cells. Upon activation by IL-12, Stat4 undergoes phosphorylation, leading to dimerization and subsequent translocation to the nucleus, where Stat4 binds to specific DNA elements to regulate gene expression. Phosphorylation of Ser 721 is particularly important as this modification is necessary for transcriptional activity of Stat4 and depends on p38 MAPK signaling, highlighting intricate regulatory mechanisms that control immune responses. anti-Stat4 antibody (E-2) specifically detects this phosphorylated form, making p-Stat4 (E-2) monoclonal antibody an invaluable tool for researchers studying immune signaling pathways and Stat4′s role in various biological processes.
