Description: eBioscience offers a panel of monoclonal antibodies to different epitopes of human Foxp3, providing useful tools for investigating the complete expression pattern of Foxp3 at the protein level, and discerning the precise subsets of Foxp3+ cells. Intracellular staining with these antibodies has demonstrated different patterns of Foxp3 expression in human PBMCs, depending on the monoclonal antibody used. These differences could be due to the expression of variants which are differentially spliced or modified post-translationally. Furthermore different intracellular staining protocols are required for each antibody, and may also contribute to the variations in observed staining patterns. Please review the flow cytometric data presented on each relevant datasheet to ensure ordering the appropriate antibody for your own uses. Please contact tech@ebioscience.com or 888.999.1371 for any additional assistance.
Please see our FAQ regarding the usage of eBioscience Foxp3 reagents.
Important: This antibody is not compatible with intracellular staining protocols which include DNase Treatment. Please use the specific buffers and protocol recommended for optimal results. (Human FoxP3 staining buffers cat. 88-5778)
The hFOXY antibody was generated against recombinant human FoxP3 protein (excluding the forkhead domain) and binds to an internal portion of human FoxP3 transcription factor,also known as FORKHEAD BOX P3, SCURFIN, and JM2. hFOXY does not crossreact with other FoxP-related family members tested including FoxP1, FoxP2, and FoxP4. Crossreactivity of hFOXY to other proteins has not been determined. The FoxP3 gene was identified as the gene defective in 'scurfy' (sf) mice.
Constitutive expression of FoxP3 mRNA was initially reported in CD4+/CD25+ regulatory T cells (Treg cells) suggesting that it may be a regulatory gene for these cells. However, recent reports demonstrate expression of FoxP3 in a subpopulation of rat and human CD8+ cells, activated conventional T cells and CD4+/CD25- cells, indicating that FoxP3 expression may not be exclusively limited to CD4+/CD25+ Treg cells. Furthermore, the majority of FoxP3 expressionanalysis so far has been limited to mRNA, which does not necessarily predict the levels of protein expression. At least one splice variant (lacking amino acids 71-105) of FoxP3 is reported in human T cells. This variant is expressed in CD8+ T cells from some donors, while both forms are present in the CD4+/CD25+ population. This may have prevented the detection of allFoxP3 expressing cells by conventional mRNA analysis such as RT-PCR and real-time PCR.
Intracellular staining of human PBMC with hFOXY reveals a subset of approximately 20% of total PBMC reacting with the hFOXY antibody however, this is subject to donor variability. Multi-color flow cytometric analysis has shown this subset to be within the CD4+ and CD8+ populations and that approximately 13-15% of CD4+/CD25+ cells stain with hFOXY. Intracellular staining of hFOXY with a polyclonal antibody, generated against a different region of human FoxP3, demonstrates 100% correlation, confirming reactivity of hFOXY to human FoxP3.
