Description
Accession
AAH26309
Source
DNA sequence encoding Human LILRB4/CD85k/ILT3 including a C-His-Avi tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human LILRB4/CD85k/ILT3 is a protein consisting of amino acid residues [Gln22-His257] ,The protein has a predicted MW of 28.6 kDa. Due to glycosylation, the protein migrates to 38-42 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
