Folate Receptor 1, also known as FOLR1, is a part of the folate receptor family whose members bind folic acid. FOLR1 binds to folate and reduced folic acid derivatives and facilitates transfer of 5-methyltetrahydrofolate and folate analogs into the cells. FOLR1 is either attaches to membranes through a glycosyl-phosphatidylinositol linkage or exists in a soluble form. FOLR1 is also needed for embryonic development and normal cell proliferation.
FOLR2 Human Recombinant is a single, glycosylated polypeptide chain containing 215 amino acids (22-230a.a) and having a molecular mass of 25.1kDa. FOLR2 is fused to a 6 a.a His tag at C-terminal, and is purified by proprietary chromatographic techniques.
The FOLR2 solution (0.25mg/ml) contains 10% glycerol and Phosphate-Buffered Saline (pH 7.4).
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 90.0% as determined by SDS-PAGE.
ED50 Range is ≤ 5 ug/ml. The Biological activity is measured by the protein’s binding ability in a functional ELISA with Folic Acid-BSA.
