Construction of full-length cDNA clone of VHSV DK-3952B genome. Six overlapping cDNA fragments covering the entire VHSV genome were assembled by ligation into a pCI vector using the EcoRI, PvuII, EcoRV, KpnI, SalI, BclI, SmaI, StuI, BsrGI and NotI restriction sites. Assembly was carried out in 3 steps; (i) cloning of six fragments (F1-F6) separately in pGEM-T vectors (see methods), and addition of hammerhead ribozyme (HHRz) at the 5′-end of F1 and hepatitis delta ribozyme (HdvRz) at the 3′-end of F6; (ii) construction of A, B and C clones into the pCI vector; (iii) assembly of the full-length clone by ligating fragments from these three clones in the pCI vector. Restriction sites artificially created (*) and naturally present in the genome are indicated. Abbreviation: CMV, cytomegalovirus immediate-early enhancer and promoter
