Description

Folate receptor 4 (FR4) is a surface receptor for folic acid (Vitamin B9).It was recently reported that FR4 is highly and constitutively expressed on mouse CD4+ CD25+ natural regulatory T cells (Treg).The high expression of this surface marker on Treg can be used in combination with CD4 and CD25 to distinguish Treg from other types of T cells.Since FR4 is a surface marker,this antibody may be used in combination with anti-CD4 and/or CD25 to sort living T reg cells for functional studies.
