IFNA4
Synonyms
IFN-alpha4a, INFA4, MGC142200
Host
HEK 293
Tag
N-human IgG1-Fc
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Purity
> 97 % as determined by SDS-PAGE
Bioactivity
Measured in antiviral assays using WISH human amnion cells infected with vesicular stomatitis virus (VSV) . The EC50 for this effect is 0.2-1 ng/mL.
Function
Cys24-Asp189
Molecular Weight
The recombinant human Fc/IFN-α4a is a disulfide-linked homodimeric protein. The reduced monomer consists of 403 amino acids and has a predicted molecular mass of 46 kDa. As a result of glycosylation, the apparent molecular mass of rh Fc/IFN-α4a monomer is approximately 50 kDa in SDS-PAGE under reducing conditions.
