Abstract:
Objective To study the immunoreaction of the recombinant proteins encoded by the fragments of ORF2 ( second open reading frames) gene of hepatitis E virus ( HEV). Methods The aimed sequence from the full-length ORF2 in clone PEH2 , which was derived from a Chinese strain of HEV,was amplified and cloned it into vector pcDNAS. 1 which was then transfected to 293 cell. Results The ORF2 protein was present in the soluble fractions of the cell lysate. The expressed protein of HEV ORF2 in 293 cells by using a plasmid pcDNA3. 1-based system showed positive on immunoblots probed against antibodies raised in BALB/c mice. Conclusion The experimental results laid a foundation for developing diagnostic reagent to detect HEV by using the expressed products of ORF2 protein.
