Form : |
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5 . Normally trehalose is added as protectant before lyophilization. |
Bio-activity : |
Immobilized Folic Acid-BSA Conjugate at 5 μg/mL (100 μL/well) can bind Human FOLR1, His Tag with a linear range of 5-78 ng/mL.Immobilized Human FOLR1, His Tag at 1 μg/mL (100 μL/well) can bind Anti-FOLR1 Antibody,Mouse IgG1 with a linear range of 0.2-1 ng/mL.Immobilized Anti-FOLR1 Antibody,Mouse IgG1 at 1 μg/mL (100 μL/well) can bind Human FOLR1, His Tag with a linear range of 1-5 ng/mL. |
Molecular Mass : |
This protein carries a polyhistidine tag at the C-terminus.The protein has a calculated MW of 26.5 kDa. The protein migrates as 35-40 KDa under reducing (R) condition (SDS-PAGE) due to glycosylation. |
Endotoxin : |
Less than 1.0 EU per μg by the LAL method. |
Purity : |
>95% as determined by SDS-PAGE.>95% as determined by SEC-MALS. |
Storage : |
For long term, the product should be stored at lyophilized state at -20°C or lower.Please protect from light and avoid repeated freeze-thaw cycles.This product is stable after at: -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution. |
Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents. |
