Description
Accession
P13688
Source
DNA sequence encoding Human CEACAM-1/CD66a including a C-His tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human CEACAM-1/CD66a is a protein consisting of amino acid residues [Gln35-Gly428] ,The protein has a predicted MW of 44.4 kDa. Due to glycosylation, the protein migrates to 68-115 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
