摘  要:
研究建立了以β-乳球蛋白标准品为包被抗原、自制抗体为一抗、辣根过氧化物酶标记的羊抗兔IgG:HRP为二抗、邻苯二胺为底物的间接竞争酶联免疫检测法(indirect competitive enzyme-linked immu nosorbent,ELISA)。同时以反相高效液相色谱法定量检测相同样品中β-乳球蛋白含量,采用t检验方法来评价间接竞争ELISA的方法定量检测β-乳球蛋白的准确性。t检验方法结果显示:在显著水平α=0.05下,该间接竞争ELISA法检测β-乳球蛋白的测量值较为准确。

摘  要:
An indirect competitive enzyme-linked immunosorbent assay(ELISA) was established with the standard β-lactoglobulin as the coated antigen, specific rabbit antibody against β-lactoglobulin as the primary antibody, horseradish peroxidase labeled goat anti-rabbit IgG:HRP as the secondary antibody and o-phenylenediamine as the substrate solution. Reversed-phase high-performance liquid chromatography(RP-HPLC) was used as the reference method. The t-test method proved that the indirect competitive ELISA for detection of β-lactoglobulin was feasible and accurate. The results of t-test at a significance level α = 0.5 showed that the indirect competitive ELISA was more accurate to detect the concentration of β-lactoglobulin.
