Immunoreaetivity Studies of Various HEV Antigen with Anti-HEV IgM of the Sear from Patients Infected with Hepatitis E Virus
Abstract: Objective To compare the Iramunoreactivity of various HEV Antigen with An ti—HEV IgM Methods Solid-phase erazyrne immunoassay(EIA )vcas developed for detecting anti HEV IgM by using synthetic peptides E30,E42,E33,and recombinant antigen from HEV ORF一2 Results Of 60 anti-HEV positive sera by using E30,E42,E33 and recombina nt antigen as coating antigen,Anti— HEV IgM positive rates were 76.7% .26,6% .18 3% and 66 7% respectively InAcute-phase and convalescence—phase sera of the patients with Hepa titis E.An ti—HEV IgM positive rate was 90% and 3 3% respectively.Condusions The HEV E30一based EIA will be very useful in the early diagnosis of Hepatitis E.
