|A DNA sequence encoding the rat FCGR2B (Q63203-1) extracellular domain (Met 1-Pro 212) was expressed, fused with a polyhistidine tag at the C-terminus.|
|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.
|> 97 % as determined by SDS-PAGE|
|Measured by its binding ability in a functional ELISA.|
Immobilized human rat FCGR2B-His (Cat:80018-R08H) at 10 μg/ml (100 μl/well) can bind biotinylated human IgG1, The EC50 of biotinylated human IgG1 is 0.3-0.8 μg/ml.
|< 1.0 EU per μg of the protein as determined by the LAL method|
|Samples are stable for up to twelve months from date of receipt at -70℃|
|The recombinant rat FCGR2B comprises 192 amino acids and predicts a molecular mass of 21.9 kDa. The apparent molecular mass of the rat FCGR2B is approximately 35-40 kDa in SDS-PAGE under reducing conditions due to glycosylation.|
|Lyophilized from sterile PBS, pH 7.4|
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
|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.|
