Description
A DNA sequence encoding the extracellular domain (Met1-Ser301) of human CD1D (P15813) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the human B2M (P61769) (Met1-Met119) constructed the plasmid 2. The two plasmids were co-expressed and the CD1D/B2M heterodimer was purified
