Active Recombinant Human CD97, Fc tagged

Specification :
| Source : HEK293 | Species : Human | Tag : Fc | Form : Lyophilized from sterile 50 mM Tris, pH 8.0.Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : Measured by its binding ability in a functional ELISA . Immobilized human CD55 at 2 μg/ml (100 μl/well) can bind human CD97 with a linear range of 1.28-32 ng/ml. | Molecular Mass : The recombinant human CD97/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 619 amino acids and predictes a molecular mass of 68.2 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh CD97/Fc monomer is approximately 100-110 kDa due to glycosylation. | Protein Length : Met 1-Gln 398 | Endotoxin : | Purity : > 90 % as determined by SDS-PAGE | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°CStore 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℃ before opening to recover the entire contents.
