Description
Accession
XP_005548617
Source
DNA sequence encoding Cynomolgus B7-H2/ICOSLG including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Cynomolgus B7-H2/ICOSLG is a protein consisting of amino acid residues [Asp19-Thr256] ,The protein has a predicted MW of 27.7 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
