Description
Accession
P17181
Source
DNA sequence encoding Human IFN alpha/beta R1 including a C-His-Avi tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human IFN alpha/beta R1 is a protein consisting of amino acid residues [Lys28-Lys436] ,The protein has a predicted MW of 50.2 kDa. Due to glycosylation, the protein migrates to 74-95 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
see methods section
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Presentation
