Recombinant human FOLR2 protein

FOLR2, also known as Folate receptor beta, is a member of the folate receptor (FLOR) family. Members of this gene family have a high affinity for folate and folic acid analogs at neutral pH. And they mediate delivery of 5-methyltetrahydrofolate to the interior of cells. It was originally thought to exist only in placenta, but is also expressed in placenta, cells of the neutrophilic lineage, and some CD34+ hematopoietic progenitor cells. FOLR2 is also upregulated on macrophages and monocytes at chronic inflammatory sites including rheumatoid arthritis synovium and glioblastoma. Recombinant human FOLR2, fused to His-tag at C-terminus, was expressed in HEK293 cell and purified by using conventional chromatography techniques.
