  • Source
    Human FOLR3, His Tag(FO3-H52H3) is expressed from human 293 cells (HEK293). It contains AA Gln 23 - Ser 245 (Accession # P41439-1 ).
    Predicted N-terminus: Gln 23
  • Molecular Characterization
    FOLR3 Structure

    This protein carries a polyhistidine tag at the C-terminus

    The protein has a calculated MW of 27.4 kDa. The protein migrates as 33-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5 with trehalose as protectant.

FOLR3 MALS images

The purity of Human FOLR3, His Tag (Cat. No. FO3-H52H3) is more than 90% and the molecular weight of this protein is around 28-42 kDa verified by SEC-MALS.


Folic acid-BSA immobilized on CM5 Chip can bind Human FOLR3, His Tag (Cat. No. FO3-H52H3) with an affinity constant of 1.03 nM as determined in a SPR assay (Biacore T200) (Routinely tested).

  • Background
    FOLR3, also know as folate receptor gamma, is a member of FRs. Folic acid and its reduced derivatives are transported via two widely expressed transporters, the reduced folate carrier (RFC) and the proton-coupled folate transporter (PCFT), and via a family of glycosyl-phosphatidylinositol (GPI)-anchored receptors with limited expression profiles known as folate receptors (FRs).Folate receptors (FR) are high affinity receptors that transport folate via endocytosis. Human FR exists in three isoforms, alpha and beta equipped with GPI anchors, and gamma not possessing a GPI anchor.
