Description
Accession
Q8SPW3
Source
DNA sequence encoding Cynomolgus Fc gamma RIIB including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Cynomolgus Fc gamma RIIB is a protein consisting of amino acid residues [Ala46-Pro224] ,The protein has a predicted MW of 21 kDa. Due to glycosylation, the protein migrates to 33-40 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
