Description
Accession
Q16552
Source
DNA sequence encoding Human IL-17A/CTLA-8 including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human IL-17A/CTLA-8 is a protein consisting of amino acid residues [Gly24-Ala155] ,The protein has a predicted MW of 18.2 kDa. Due to glycosylation, the protein migrates to 16-30 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
