Provider: Invitrogen Antibodies
Product name: FOXP3 Monoclonal Antibody (150D/E4), PE, eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: eBioscience offers a panel of monoclonal antibodies to different epitopes of human/primate and mouse/rat Foxp3 protein, providing useful tools for investigating the complete expression pattern of Foxp3 at the protein level, and discerning the precise subsets of Foxp3+ cells. Other antibodies to Foxp3 available from eBioscience, which have been used significantly in scientific literature, include the anti-human Foxp3 PCH101 (cat. 72-5776) and ebio7979 (cat. 12-7979), and the anti-mouse/rat Foxp3 FJK-16s (cat. 72-5775). The 150D/E4 has been mapped to the splice region in Exon 2 found in human cells. The splicing of this region has not been shown to occur in mouse. Characterization of this antibody to the splice variant has been limited to epitope mapping. It should be noted that other antibodies such as PCH101 and 236A/E7 will recognize both the spliced and full length forms of the Foxp3 protein and stain more intensely than 150D/E4 and FJK-16s in human cells.

Experimental details: Figure 2. Regulatory T cell (Treg) depletion abrogates atherosclerosis regression. A , Experimental design: Atherosclerosis was established in C57BL6&solJ mice by injection of adeno-associated virus (AAV)-PCSK (proprotein convertase subtilisin&solkexin type)-9 followed by Western diet feeding for 20 wk (Baseline). Mice were then switched to chow diet and atherosclerosis regression was initiated by apoB (apolipoprotein B)-antisense oligonucleotide (ASO)-mediated lipid lowering in conjunction with anti-CD25 or IgG isotype control antibody treatment for 3 wk. B , Plasma total cholesterol, HDL (high-density lipoprotein) and non-HDL cholesterol, and triglyceride levels at baseline and after regression &plus IgG anti-CD25 treatment (n=11 mice&solgroup). C , Representative flow cytometric analyses of CD4 &plus CD25 &plus cells in the circulation of mice treated with IgG or anti-CD25 during atherosclerosis regression. D , Quantification of FoxP3 &plus CD25 &plus cells in peripheral blood (n=5&solgroup), thymus (n=5&solgroup), and spleen (n=9&solgroup) of mice by flow cytometry. Data are mean+-SEM and are representative of 2 independent experiments. P values were determined by a Student t test. E , Representative immunofluorescence staining for FoxP3 in aortic root plaques from mice at baseline and after regression &plus IgG or anti-CD25 treatment (n=6 mice&solgroup).

Experimental details: Fig. 4 mTEC hi -restricted expression of USA preferentially induces T reg differentiation. Littermate control (LMC), CRP, and INS2 Tg mice (CD45.2, Thy1.2) were irradiated and reconstituted with 1% OT-II (CD45.2, Thy1.1) and 99% WT (CD45.1, Thy1.2) bone marrow. The hematopoietic chimeras were analyzed 6-8 weeks post-irradiation. a Proportion of mature TCRbeta hi CD4 + SP OT-II thymocytes among total live cells and absolute number of live CD4 + SP OT-II thymocytes. b Proportion of OT-II cells within the CD4 + T cell population in the peripheral lymph nodes. c Representative flow plots of CD25 and FoxP3 expression on OT-II T cells. d Proportion and absolute cell number of CD25 + Foxp3 + OT-II T cells in the thymus. e Proportion of CD25 + Foxp3 + OT-II T cells in the lymph nodes. (mean +- SEM, n = 17 LMC, 8 CRP, 10 INS2, from three independent experiments). All p -values indicated are calculated by Kruskal-Wallis test followed by Dunn''s post-hoc comparisons to LMC, two-sided. ** p < 0.01 relative to LMC. Source data are provided as a Source Data file.
