Avi&Fc |
Protein Length : |
21-153 a.a. |
Form : |
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization. |
Bio-activity : |
Immobilized Biotinylated Human IL-2, Fc,Avitag at 1 μg/mL (100 μL/well) on streptavidin precoated (0.2 μg/well) plate, can bind Human IL-2 R alpha, His Tag with a linear range of 1-39 ng/mL.Immobilized Human IL-2 R alpha, Fc Tag at 5 μg/mL (100 μL/well) can bind Biotinylated Human IL-2, Fc,Avitag with a linear range of 0.6-10 ng/mL. |
Molecular Mass : |
This protein carries a human IgG1 Fc tag at the N-terminus and an Avi tag at the C-terminus.The protein has a calculated MW of 43.7 kDa. The protein migrates as 45-50 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. |
Proteinlength : |
Ala21-Thr153 |
Endotoxin : |
Less than 1.0 EU per μg by the LAL method. |
Purity : |
>95% as determined by SDS-PAGE. |
Storage : |
For long term, the product should be stored at lyophilized state at -20°C or lower.Please 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. |
