Four groups of oligonucleotides were successively cloned in pMD18-T vector to obtain four large fragments. Ligation of these four fragments resulted in a cloned DNA MgE717 coding for the 29～268 amino acid region of gE. Sequencing result showed that there is a mutation at 255 amino acid, Asn instead of Asp.
