Abstract Varicella zoster virus (VZV) glycoprotein E (gE) is the main candidate protein for VZV subunit vaccine. Unfortunately, the expression of gE in prokaryotic expression was mainly found in the inclusion body. In this study, a deletion of N-terminal 30 amino acids of gE was constructed on pET32a, expressed in BL21 (DE3). The soluble gE was purified and used to make polyclonal antibodies in BALB/c mice. The titer and specificity of polyclonal antibodies were determined by enzyme linked immunosorbent assay (ELISA) and indirect immunofluorescence. The results showed that the soluble recombinant gE produced by BL21/pET32a-VZV gE system is a practical way for vaccine development.
