Amplification and cloning of herpes simplex virus type 2 glycoprotein G from an Iranian isolate

Herpes Simplex Virus type-2 (HSV-2) is the main cause of genital herpes infection. Its prevalence is increasing worldwide and varies widely with generally higher rate in developing than developed countries and urban than rural areas. HSV-2 Iranian isolate was propagated in HeLa cell line. The viral genome was extracted by phenol-chloroform and used as template in nested polymerase chain reactions (n-PCR) to amplify gG-2 gene. The amplified gene was cloned into a cloning vector (pTZ57R/T) and transformed into competent E. coli DH5a. The recombinant vector encoding the gene of interest was confirmed by restriction enzyme analysis and sequencing.
