Tag : |
hFc |
Form : |
Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. |
Bio-activity : |
Measured by its binding ability in a functional ELISA. Immobilized recombinant human IL13RA2 at 8 μg/ml (100 μl/well) can bind IL13 with a linear range of 0.25-8.0 ng/ml. |
Molecular Mass : |
The recombinant human Fc/IL13 chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 349 amino acids and predicts a molecular mass of 39 kDa. The apparent molecular mass of rhIL13/Fc monomer is approximately 50-55 kDa in SDS-PAGE under reducing conditions due to glycosylation. |
Proteinlength : |
Gly21-Asn132 |
Endotoxin : |
< 1.0 EU per μg of the protein as determined by the LAL method |
Purity : |
> 98 % as determined by SDS-PAGE |
Storage : |
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
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. |
