FR4 (Folate receptor 4) Rat anti-Mouse, APC, Clone: 12A5, BD
Rat Monoclonal Antibody
Marca: BD Biosciences 560318
Descripción
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 35kDa 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 Nanve 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.
