Molecular Characterization

Other Tags and Version Biotin & Other Labeled Version
Biotinylated Human CD3E&CD3G Heterodimer Protein, His,Avitag&Tag Free is produced by co-expression of CD3E and CD3G, has a calculated MW of 18.6 kDa (CD3E) and 14.7 kDa (CD3G). Subunit CD3E is fused with a polyhistidine tag at the C-terminus, followed by an Avi tag and subunit CD3G contains no tag at the C-terminus. The reducing (R) heterodimer protein migrates as 20-24 kDa and 25-28 kDa when calibrated against Star Ribbon Pre-stained Protein Marker due to glycosylation.
