Construction of a cDNA Libray of the Bovine Viral Diarrhea Virus Genome
Abstract: ovine viral diarrhea virus(BVDV)InL genomic RNA was used as a template to synthesizeDNA by reverse transcriptase.The ds cDNA was synthesized by RNase H-DNA polymerase,and waslsetrted into the Pst I site of the pUC8 vector by dC-dG homopolymeric tailing and ligation.After beig transformed to E.coli JM101,the recombinants were screened by in situ hybridization with γ- ̄(32)P-ATP labeled purified BVDV RNA,Restrict ion enzyme ana lysis sho wed that the largest cDNA insertwas 12kb-13kb,it almust covered the BVDV...
