Recombinant Human FOLR1 Protein, hFc Tag, Yisheng (CAT#: STEM-CT-0241-ZJF)

The Recombinant Human FOLR1 Protein, hFc Tag manufactured by Yisheng is suitable for targeting FOLR1-positive cells in cell therapy.

Source: Recombinant Human FOLR1 Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Arg25-Met233.[ Uniprot| P15328]
Molecular Weight: The protein has a predicted MW of 51.3 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result.
Endotoxin: Less than 1EU per μg by the LAL method.
Purity: > 95% as determined by Tris-Bis PAGE and HPLC
Activity: ELISA Data: Immobilized Human FOLR1, hFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Anti-FOLR1 Antibody, hFc Tag with the EC50 of 14.6ng/ml determined by ELISA.
Formulation: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
Reconstitution: Centrifuge tubes before opening. Reconstituting to a concentration more than 100
μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Shipped with ice pack.
Stored at -25~-15℃ for 1 year from date of receipt.
2-7 days, 2 ~8 ℃ under sterile conditions after reconstitution.
3 months, -25~-15℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
For safety and health, please wear lab coats and disposable gloves for operation.
