NS 4 gene of hepatitis C virus was amplified by RT - PCR using RNA template isolated from anti - HCV positive serum of a blood donor from Hebei province in China. The amplified fragmint (abeut 900bp)was cloned into plasmid pET17Xb and the recombinant plasmid was des-ignated pETNS 4. SDS - PAGE analyses showed that a 65 ari fused protien was expressed in E.coli BL21 (DE3 ) harboring pETNS 4 and the expression level of the protien was 24 %. The cDNA fragment of insert of pETNS 4 was sequenced with the dideoxy...
