酶免疫技术作为三大免疫标记技术之一,以其敏感性高、特异性强、快速易行的特点在生物学、医学基础研究及临床诊断上得到了广泛地应用,并正在不断改进和发展。70年代初,有人在非标记抗体技术的基础上,将过氧化物酶-抗过氧化物酶(PAP)复合物用于免疫酶技术,使该技术的敏感性得到了提高,并使试剂更加通 As one of the three major immunolabeling technologies, enzyme immunoassay has been widely used in biology, medical basic research and clinical diagnosis due to its high sensitivity, specificity and rapidity, and is being continuously improved and developed . In the early 1970s, the use of a peroxidase-anti-peroxidase (PAP) complex on immune enzyme technology based on non-labeled antibody technology led to increased sensitivity and more reagents through
