利用多肽合成技术在戊型肝炎病毒（ＨＥＶ）的结构区内的开放读码框（ＯＲＦ）－２和ＯＲＦ－３区合成了Ｐ１、Ｐ２二条具有明确抗原表位的合成多肽，作为ＥＩＡ法抗－ＨＥＶ诊断试剂的固相抗原测定抗－ＨＥＶ。在７８例急性甲型肝炎中抗－ＨＥＶ检出率为７．８％，慢性乙型肝
Polypeptide synthesis was used to synthesize P1 and P2 synthetic peptides with definite epitopes in the open reading frames (ORF) -2 and ORF-3 regions of the HEV structural domain as EIA method Anti-HEV Assay for Solid Phase Antigens from HEV Diagnostic Reagents. In 78 cases of acute hepatitis A anti-HEV was detected in 7.8% of chronic hepatitis B.
