Foxp3, a 49-55 kDa protein, is a member of the forkhead\/winged-helix family of transcriptional regulators, and was identified as the gene defective in 'scurfy' (sf) mice. Constitutive high expression of foxP3 mRNA has been shown in CD4+CD25+ regulatory T cells (Treg cells), and ectopic expression of foxp3 in CD4+CD25- cells imparts a Treg phenotype in these cells.\u003c\/p\u003e\u003cp\u003eImmunoblotting with FJK-16s antibody has mapped the epitope to amino acids 75-125 of the mouse Foxp3 protein. In the human, this region has been shown to be alternatively spliced at the mRNA level. Both the alternatively-spliced and non-spliced isoforms are present in the CD4+CD25+ subset of lymphocytes. Preliminary RT-PCR experiments have not revealed this alternatively-spliced isoform in mouse splenocytes, suggesting different gene regulation in the mouse and human.\u003c\/p\u003e\u003cp\u003ePlease note that FJK-16s has been optimized for use with the Foxp3\/Transcription Factor Buffer Staining Set (\u003ca href=\"https:\/\/www.thermofisher.com\/order\/catalog\/product\/00-5523-00\"\u003eProduct # 00-5523-00\u003c\/a\u003e).

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™ 421 (BV421) is a dye that emits at 423 nm and is intended for use on cytometers equipped with a violet (405 nm) laser.
