Description

Rat Monoclonal Antibody

The monoclonal antibodies TH6 and 12A5 recognize Folate Receptor 4(FR4), also known as the membrane folate- binding protein 3(FBP3). FR4 is a heavily glycosylated 35 kD receptor expressed exclusively in lymphoid tissue and an isoform of the family of receptors that recognize the essential nutrient folic acid. Natural T regulatory cells constitutively express high levels of FR4. Differential expression of FR4 in combination with CD25 can distinguish four functionally distinct CD4+ T cell subpopulations; Natural Tregs, effector T cells, memory-like T cells and Naοve T cells. FR4hi CD25+ expressing CD4+ T cells also express high amounts of Foxp3, GITR and CTLA-4.Monoclonal antibody TH6 and 12A5 stained CD25+CD4+ T cells at a higher level than other CD4+ or CD8+ T cells. In addition, in vivo injection of TH6 monoclonal antibody reduced the number of CD25+CD4+ T cells and CD25-CD4+ T cells in peripheral blood. Clone 12A5 has been demonstrated to work in western blot. Clones TH6 and 12A5 do not block one another in a flow cytometric assay.

The antibody was conjugated to BD Horizon™ BUV395 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye has been exclusively developed by BD Biosciences to have minimal spillover into other detectors, making it an optimal choice for multicolor flow cytometry. With an Ex Max at 348 nm and an Em Max at 395 nm, BD Horizon BUV395 can be excited with a 355 nm laser and detected with a 379/28 filter. BUV395 is a UV-excitable dye that has been developed exclusively by BD Biosciences. With an excitation max of 348 nm and emission max of 395 nm, BUV395 can be excited by the 355nm laser and detected in a 379/28 filter. This dye is optimal for multicolor flow cytometry because it has little to no spillover into other detectors.
