Abstract: Partial ATPase/RNA helicase functional domain of NS3 genes of CSFV SHIMEN rain and C rain were amplified by RT-PCR;The recombinant plasmids pET-N
S3 SMand p ET-NS3C were obtained after being cloned them into expression vector pET-28a(+); And then the 54 kD target proteins were produced by inducing with 0.8 mmol/L IPTG;Western blotting showed that the expressed proteins couldn't be recognized by superserum against csfv.And ELISA showed that the expressed proteins could be recognized by superserum against csfv.
