    Mediates delivery of 5-methyltetrahydrofolate to the interior of cells
  • Recombinant
    Yes
  • Source
    HEK293 cells
  • Purity by SDS PAGE
    ≥95%
  • Assay
    SDS-PAGE
  • Biological activity
    Measured by its binding ability in a functional ELISA. When Folic Acid Bovine Serum Albumin was coated at 5 ug/ml (100 ul/well), the concentration of rhFOLR2 that produces 50% of the optimal binding response was found to be approximately 0.15-1.1 nM.
  • Results
    Measured by its binding ability in a functional ELISA. When Folic Acid Bovine Serum Albumin was coated at 5 ug/ml (100 ul/well), the concentration of rhFOLR2 that produces 50% of the optimal binding response was found to be approximately 0.15-1.1 nM.
  • Molecular Weight
    This protein is fused with 6×his tag at the C-terminus and has a calculated MW of 26 kDa expressed. The predicted N-terminus is Thr17. Protein migrates as 30-33 kDa in reduced SDS-PAGE resulting from glycosylation.

  • Physical form description
    Lyophilized from 0.22 um filtered solution in PBS, pH 7.4. Normally Mannitol or Trehalose is added as protectants before lyophilization.
  • Reconstitution Instructions
    Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
  • Background Information
    Folate receptor beta, also known as Folate receptor 2, FBP, FOLR2, BETA-HFR, FBP/PL-1, FR-BETA, FR-P3, and is a member of the folate receptor (FOLR) family which mediates delivery of 5-methyltetrahydrofolate to the interior of cells. This protein has a 68% and 79% sequence homology with the FOLR1 and FOLR3 proteins, respectively. The FOLR2 protein was originally thought to exist only in placenta, but is also detected in spleen, bone marrow, and thymus. FOLR2 is predominantly expressed in placenta, cells of the neutrophilic lineage, and some CD34+ hematopoietic progenitor cells. It is upregulated on myeloid leukemias, head and neck squamous cell carcinomas, and several nonepithelial cancers. It is also upregulated on macrophages and monocytes at chronic inflammatory sites including rheumatoid arthritis synovium and glioblastoma. FOLR2 is a marker for macrophages generated in the presence of M-CSF, but not GM-CSF. Its expression correlates with increased folate uptake ability. Folate conjugates of therapeutic drugs are a potential immunotherapy tool to target tumor-associated macrophages.
  • Handling
    Centrifuge the vial prior to opening.
  • Usage
    For Research Use Only! Not to be used in humans
  • Properties
    Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
