[0035] 1. Amplification of the target gene:
[0036] HSV-2 gD was successively constructed on the pcDNA3.1(+) plasmid vector (purchased from Invitrogen, the same below) (the experimental strain of HSV-2 was HG52 strain, purchased from LGC Pharmaceutical Impurity Standard Company, Royal Laboratory of England) (GenBank : Z86099.2) envelope glycoprotein gene and adjuvant gene CCL28 (Kai Hu. JOURNAL OF IMMUNOLOGY, Aug. 2013, p.1935-1947), the molecular formulas are: pcDNA3.1(+)-Xba I-gD- PmeI, pcDNA3.1 (+)-HindIII-CCL28-KpnI, named after pgD (for containing the pcDNA3.1 (+) plasmid of the nucleotide sequence shown in SEQ ID NO.1) and pCCL28 (for containing the nucleotide sequence shown in SEQ ID NO.1) respectively pcDNA3.1 (+) plasmid with the nucleotide sequence shown in NO.2), and the primer sequences for amplifying the target fragment are shown in Table 1.
