FOLR4 in Human Melanoma. FOLR4 was detected in immersion fixed paraffin-embedded sections of human melanoma using Rat Anti-Human FOLR4 Monoclonal Antibody (Catalog # MAB6328) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS017) and counterstained with hematoxylin (blue). Specific staining was localized to the plasma membranes of cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Preparation and Storage

Background: FOLR4

FOLR4 (Folate Receptor 4), also known as FR4, Folate Receptor δ, 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, FR4^hiCD25^hi expression defines T reg cells, FR4^loCD25⁺ expression pattern identifies effector memory T cells, and a FR4^hiCD25^- 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.
