Description
Accession
P79339
Source
DNA sequence encoding Cynomolgus IL-4 including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Cynomolgus IL-4 is a protein consisting of amino acid residues [His25-Ser153] ,The protein has a predicted MW of 16.03 kDa. Due to glycosylation, the protein migrates to 23-28 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
