The monoclonal antibody eBioTh6 recognizes FR4, also known as FR δ and FBP3 (folate binding protein3). FR4 is a heavily glycosylated 35 kD receptor for folic acid and the physiologic circulating form of the vitamin, N5-methyltetrahydrofolate. Natural T regs have high levels of FR4 and together with CD25 can be used to distinguish natural Tregs, effector T cells, memory-like T cells and naïve T cells. In vivo studies with eBioTH6 show a decrease in the number of CD4+CD25+ cells and an enhanced tumor response leading to the elimination of advanced stages of tumors.

Based on co-staining studies, the epitopes recognized by eBioTH6 and eBio12A5 (cat 51-5445) are different thereby allowing functional studies with TH6 to be evaluated with eBio12A5.
