Description
A DNA sequence encoding the extracellular domain (Met 1-Ala 105) of mouse CD3D (P04235) was fused with a flag tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the extracellular domain (Met 1-Asp 108) of mouse CD3E (P22646) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the mouse CD3D/CD3E heterodimer was purified
