Description
Accession
G7PSE7
Source
DNA sequence encoding Cynomolgus PD-L1/B7-H1 including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Cynomolgus PD-L1/B7-H1 is a protein consisting of amino acid residues [Phe19-Arg238] ,The protein has a predicted MW of 26 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
