Scientific Data Images for Human FOLR4 Antibody
Detection of Human FOLR4 by Western Blot.
Western blot shows lysates of A431 human epithelial carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human FOLR4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6328) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for FOLR4 at approximately 36 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.Applications for Human FOLR4 Antibody

Background: FOLR4
FOLR4 (Folate receptor 4; also FR4 and folate receptor delta and folate binding protein 3) is a 34‑36 kDa member of the folate receptor family of molecules. Based on mouse, it appears to be a marker for subsets of T cells. In particular, and in conjunction with CD25, FR4hiCD25hi expression defines T reg cells, FR4loCD25+ expression pattern identifies effector memory T cells, and a FR4hiCD25- combination characterizes central memory T cells. Mature human FOLR4 is 225 amino acids (aa) in length (aa 20‑244). It contains virtually no identifiable motifs. There is one potential splice variant that shows a five aa substitution for aa 111‑116. Over aa 134‑220, human FOLR4 shares 72% aa identity with mouse FOLR4.
