Description

Description: The monoclonal antibody eBioTh6 recognizes FR4, also known as FR delta 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 naive 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 are different thereby allowing functional studies with TH6 to be evaluated with eBio12A5. Applications Reported:This eBioTH6 antibody has been reported for use in flow cytometric analysis, immunoprecipitation and in vivo depletion. Applications Tested: This eBioTH6 antibody has been tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 0.25 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. Storage and handling: Use in a sterile environment. Filtration: 0.2 μm post-manufacturing filtered. Purity: Greate...
