Multiple-cloning-site plasmids for the rapid construction of recombinant poxviruses

D B Boyle et al. Gene. 1985.

Abstract

Plasmid vectors containing multiple cloning sites suitable for the rapid insertion of protein-coding sequences into poxviruses have been constructed. They are based on pUC plasmids and carry the thymidine kinase (TK) gene of vaccinia virus interrupted by a vaccinia virus promoter. Six unique restriction enzyme sites (BamHI, SalI/HincII, PstI, HindIII, EcoRI), located within 40 bp of vaccinia virus promoters transposed from the HindIII-F or HindIII-C fragment of the vaccinia virus genome, allow rapid insertion of foreign-protein-coding sequences into these plasmids. Such plasmids can be used to construct recombinant poxviruses expressing foreign proteins using marker-rescue recombination techniques and selection for TK negative viruses. Vaccinia viruses expressing the haemagglutinin (HA) gene of swine influenza virus, A/NJ/11/76 (H1N1), have been constructed.
