Description
The protein encoded by this gene is a member of the folate receptor family. Members of this gene family bind folic acid and its reduced derivatives, and transport 5-methyltetrahydrofolate into cells. This gene product is a secreted protein that either anchors to membranes via a glycosyl-phosphatidylinositol linkage or exists in a soluble form. Mutations in this gene have been associated with neurodegeneration due to cerebral folate transport deficiency. Due to the presence of two promoters, multiple transcription start sites, and alternative splicing, multiple transcript variants encoding the same protein have been found for this gene.
Bio-activity
Measured in a competitive binding assay.
When Folic Acid-Bovine Serum Albumin is immobilized at 5 μg/mL (100 μL/well), Recombinant Mouse (rm) FOLR1 inhibits 50% binding of biotinylated rmFOLR1 (7.9 nM) at the concentration range of 30-120 nM.
Storage

12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
