Active Recombinant Human CSF2RB protein, His-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : His | Form : Lyophilized from sterile PBS, pH 7.4. 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 CD131 at 10 μg/ml (100 μl/well) can bind human Fc-GMCSF, The EC50 of human Fc-GMCSF is 250-500 ng/ml. | Molecular Mass : The recombinant human CSF2RB consists of 438 amino acids and has a predicted molecular mass of 50 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh CSF2RB is approximately 50-55 kDa. | Protein Length : Met1-Trp443 | Endotoxin : | Purity : > 97 % as determined by SDS-PAGE | Storage : Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. 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.
