Description
Accession
P01562
Source
DNA sequence encoding Human IFN alpha 1 including a C-hFc tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human IFN alpha 1 is a protein consisting of amino acid residues [Cys24-Glu189] ,The protein has a predicted MW of 46.14 kDa. Due to glycosylation, the protein migrates to 48-55 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
