Mouse FOLR4 Antibody Summary

Species Reactivity

Mouse

Specificity

Detects mouse FOLR4 in direct ELISAs and Western blots. In direct ELISAs, no cross-reactivity with recombinant mouse (rm) FOLR1, rmFOLR2, recombinant human (rh) FOLR3, or rhFOLR4 is observed. In Western blots, no cross-reactivity with rhFOLR1, 2, or 3 is observed.

Detection of Mouse FOLR4 by Western Blot. Western blot shows lysates of mouse CD4⁺CD25^-T cells and mouse CD4⁺CD25⁺T cells. PVDF membrane was probed with 1 µg/mL of Rat Anti-Mouse FOLR4 Monoclonal Antibody (Catalog # MAB6124) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody. A specific band was detected for FOLR4 at approximately 35 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: FOLR4

FOLR4 (folate receptor 4; also FR4, FR-d and FOLBP-3) is a 35 kDa glycoprotein member of the folate receptor family. It is found on mouse Treg cells, particularly those classified as natural, and CD4⁺ CD25^- T cells that produce low amounts of IFN-gamma. Although folate family receptors can internalize folate, they are generally not the principal conduits for folate uptake. Mouse FOLR4 preproprecursor is 244 amino acids (aa) in length. It contains a 19 aa signal sequence plus a 225 aa proform. While there are no definitive structural motifs, there is presumably a C-terminal propeptide that gives rise to a GPI-linkage. There are three potential isoforms. One is 37 kDa in size and shows a 36 aa insertion after Glu155. Two others show a deletion of aa 47-109, and a 17 aa substitution for aa 157-244. Over aa 20-100, mouse FOLR4 shares 84% and 70% aa identity with rat and human FOLR4, respectively.
