A process for detecting the presence of an antigen in a specimen is described, which process comprises:
A) contacting said specimen with a substrate coated with antibodies of said antigen, incubating the contacted substrate and washing the substrate;
B) contacting the washed material of step A) with a hapten conjugated antibody against said antigen, incubating the so-contacted material and washing the so-incubated material;
C) contacting the washed material of step B with a radioactive material labeled or enzyme containing antihapten antibody, incubating the so-contacted material and washing the same; and
D) effecting radioimmunoassay if said antibody is radioactive or enzyme labeled immunoassay if said antibody contains an enzyme moiety.
Quantitative determination of the antigen in the specimen is effected by comparing the counts of the radioimmunoassay or the concentration of enzyme against a standard as by photocolormetric methods.
                            描述了一种检测标本中是否存在抗原的方法,该方法包括
A) 将标本与涂有抗原
抗体的基质接触,孵育接触的基质并清洗基质;
B)将步骤 A)中洗涤后的材料与针对所述抗原的单抗结合
抗体接触,孵育如此接触的材料并洗涤如此孵育的材料;
C) 将步骤 B 中洗涤后的材料与标记有放射性物质或含有酶的抗组蛋白
抗体接触,孵育接触后的材料并洗涤;以及
D) 如果所述
抗体具有放射性,则进行放射免疫分析;如果所述
抗体含有酶分子,则进行酶标记免疫分析。
通过比较放射免疫分析的计数或酶的浓度与标准(如光电比色法),对样本中的抗原进行定量测定。
