Description
(1) HBc抗原結合粒子の作製
リコンビナントHBc抗原結合粒子を、次の通り調製した。
マウス抗ヒトIgGモノクローナル抗体(富士レビオ社製)とウシ小腸由来アルカリホスファターゼ(オリエンタル酵母社製)とをヨシタケらの方法(Yoshitakeet al., J.Biochem. 1982, 92(5), p1413-1424)により結合させ、ALP酵素標識抗体を調製した。
標準曲線の作成に用いる基準試料は、抗HBc抗体用WHO第1国際標準品(WHO International Standard First International Standard for anti-Hepatitis B core antigen (anti-HBc), plasma, human NIBSC code: 95/522)を基にIgG型抗HBc抗体濃度(IU/ml)を決定したB型慢性肝炎患者由来検体を適宜希釈して準備した。
(3)に記載した測定方法に従って検体を測定した。測定対象は、長崎医療センターにて臨床症状および各種血液検査所見よりB型急性肝炎と診断された30例、B型慢性肝炎と診断された130例、およびHBs抗原・抗体ともに陰性である非B型肝炎の30例であった。検体として、−20℃にて保管した上記190例の血清を測定前に溶解して用いた。
検体中のIgG型抗ヒトHBc抗体およびIgM型抗ヒトHBc抗体を含む抗ヒトHBc抗体の総量を測定し、高力価、低力価判定を利用することにより、B型急性肝炎とB型慢性肝炎とを従来法で鑑別した。なお、総HBc抗体は、ルミパルスプレスト(登録商標)HBcAb(富士レビオ社製)を用いて競合法により測定した。検体は、上記(4)で用いた検体と同一検体を用いた。
