Description
Accession
BAA13520
Source
DNA sequence encoding Mouse SIRP alpha/CD172a including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Mouse SIRP alpha/CD172a is a protein consisting of amino acid residues [Lys32-Asn373] ,The protein has a predicted MW of 39 kDa. Due to glycosylation, the protein migrates to 65-85 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
