Product Specific Information

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: Greater than 90%, as determined by SDS-PAGE.

Endotoxin Level:Less than 0.001 ng/µg antibody, as determined by LAL assay.

Aggregation:Less than 10%, as determined by HPLC.
