Human FOLR1 Protein
Recombinant Human FOLR1 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Arg25-Met233 [Accession | P15328].
The protein has a predicted MW of 27.5 kDa. Due to glycosylation, the protein migrates to 38-45 kDa based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
Less than 1 EU per μg by the LAL method.
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Human FOLR1 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.
The purity of Human FOLR1 is greater than 95% as determined by SEC-HPLC.
Immobilized Human FOLR1, His Tag at 1 μg/ml (100 μl/Well) on plate.Dose response curve for Anti-FOLR1 Antibody, hFc Tag with the EC50 of 4.6 ng/ml determined by ELISA.
Folate Receptor 1 (FOLR1), also known as Folate Receptor alpha and Folate Binding Protein (FBP), is a 37 - 42 kDa protein that mediates the cellular uptake of folic acid and reduced folates. Dietary folates are required for many key metabolic processes including nucleotide and methionine synthesis, the interconversion of glycine and serine, and histidine breakdown. FOLR1 binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate and folate analogs into the interior of cells. Has high affinity for folate and folic acid analogs at neutral pH.
