< 1.0 EU per μg of the protein as determined by the LAL method
Measured by its binding ability in a functional ELISA. Immobilized cynoCD32B-His (Cat:90014-C08H) at 10 μg/ml (100 μl/well) can bind biotinylated human IgG1, The EC50 of biotinylated human IgG1 is 0.17-0.41 μg/ml.
A DNA sequence encoding the Cynomolgus (Macaca fascicularis) CD32b (AAL92097.1) extracellular domain (Met 1-Pro 217) was fused with a polyhistidine tag at the C-terminus.
The recombinant cynomolgus CD32b consists of 184 amino acids and has a calculated molecular mass of 20.9 kDa. The apparent molecular mass of the recombinant protein is approximately 28-33 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Lyophilized from sterile PBS, pH 7.4 Please 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.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃ Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
