IRF4 is a 52 kDa transcription factor with roles in B cell, T cell and macrophage function. In B cells, IRF4 is highly expressed in mature plasma cells and plays a crucial role in their differentiation. IRF4 has been shown to interact with PU.1 and control the transcription of many B cell-specific genes including Prdm1, which encodes Blimp1. In T cells, IRF4 has been implicated in regulatory T (Treg), Th2, Th9 and Th17 cell development and function. This transcription factor is upregulated upon T cell activation and is expressed in mature T cells. Studies have shown that IRF4 directly induces Blimp1 expression in Tregs, leading to IL-10 expression. IRF4 has also been demonstrated to be involved in macrophage polarization and regulation. Lastly, in addition to its roles in normal immune function, IRF4 expression has been reported to be upregulated in many blood-related cancers.\u003c\/p\u003e\u003cp\u003eApplications Reported: This 3E4 antibody has been reported for use in intracellular staining followed by flow cytometric analysis.\u003c\/p\u003e\u003cp\u003eApplications Tested: This 3E4 antibody has been tested by intracellular staining followed by flow cytometric analysis of normal human peripheral blood cells using the Foxp3\/Transcription Factor Staining Buffer Set (\u003ca href=\"https:\/\/www.thermofisher.com\/order\/catalog\/product\/00-5523-00\"\u003eProduct # 00-5523-00\u003c\/a\u003e) and protocol.

This may be used at less than or equal to 1.0 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells\/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.\u003c\/p\u003e\u003cp\u003eBrilliant Violet™ 480 (BV480) is a dye that emits at 479 nm and is intended for use on cytometers equipped with a violet (405 nm) laser.
