【摘要】:目的:應(yīng)用點免疫金滲濾法篩選適宜膠體金標記的抗人IgG(以下簡稱二抗),并運用多個評價指標進行比較和分析。方法:選擇三個不同公司的二抗用膠體金標記,根據(jù)棋盤滴定法確定最佳標記條件;運用點免疫金滲濾法對三種二抗的膠體金標記后檢測效能進行比較,采用包蟲病人和健康對照血清,用包蟲病特異性抗原檢測包蟲病患者血清中的特異性抗體,評價最優(yōu)的二抗,并與酶聯(lián)免疫吸附測定法進行比較。結(jié)果:A、B、C三種二抗標記的最佳標記條件為:p H均為8.5,加入量分別為38.4、24、19.2μg/ml,綜合評價二抗B檢測效能最優(yōu)。將其與酶聯(lián)免疫吸附測定法檢測效能進行比較,兩種方法檢測結(jié)果的Kappa=0.895(P0.05),吻合度較強。結(jié)論:應(yīng)用點免疫金滲濾法,以及本文提出的評價指標,能夠篩選出最佳二抗,對檢測試劑盒中二抗的選擇具有重要的參考價值。
[Abstract]:Objective: the application of dot immunogold filtration assay for screening of colloidal gold labeled anti human IgG (hereinafter referred to as the two anti), and the use of multiple evaluation indexes were compared and analyzed. Methods: three different companies with two anti colloidal gold, according to determine the optimal labeling conditions with chessboard titration; immune gold filtration assay to compare three kinds of colloidal gold labeled anti two note after detection efficiency, the patients with hydatid disease and healthy control serum, with specific antibody of echinococcosis specific antigen in sera of patients with hydatid disease detection, evaluation of optimal two antibody, and ELISA method were compared. Results: A B, C, the best labeling conditions three two anti markers: P H = 8.5, adding 38.4,24,19.2 g/ml respectively, two comprehensive evaluation of anti B detection efficiency. The optimal ELISA detection efficiency comparison, the test results of the two methods Kappa=0.895 (P0.05) has strong agreement. Conclusion: the application of dot immunogold filtration assay and the evaluation index proposed in this paper can screen the best two resistance, which has important reference value for the selection of the two antibody in the detection kit.
