Anti-FOXP3 (Forkhead Box P3, AIID, DIETER, IPEX, JM2, PIDX, SCURFIN, XPID)

FOXP3 (a 431 amino acid protein) is a member of the forkhead/winged-helix family of transcriptional regulators and is highly conserved across mammals. FOXP3 is essential for normal immune homeostasis. FOXP3 is stably and constitutively expressed at a high level in CD25 + CD4 positive regulatory T cells, at low level in CD4 positive/CD25 negative cells, and is absent in CD4 negative/CD8 positive T cells. FOXP3 may be a master regulatory gene and a more specific marker of regulatory T cells than other T cells. Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:8,000, Western Blot: 1-3ug/ml, Immunohistochemistry: 4-6ug/ml, Optimal dilutions to be determined by the researcher.
