该测定依赖于抗原-抗体相互作用的原理,并利用酶和比色检测来量化目标分子,主要用于检测和量化生物样品中特定蛋白质、肽、抗体或抗原的存在。 ELISA测定通常应用于各个领域,包括临床诊断、药物研究和生命科学基础研究。 酶联免疫吸附测定法(ELISA)是一种固相免疫测定技术,由瑞典学者Engvall、Perlmann和荷兰学者Van Weerman、Schuurs于1971年分别提出。 酶联免疫吸附试验 (以下简称ELISA) :是酶免疫测定技术中应用最广的技术。 其基本方法是将已知的抗原或抗体吸附在固相载体 ( 聚苯乙烯微量反应板 ) 表面,使酶标记的抗原抗体反应在固相表面进行,用洗涤法将液相中的游离成分洗除。

Elisa has been used as a diagnostic tool in medicine, plant pathology, and biotechnology, as well as a quality control check in various industries Learn about the different methods for performing an elisa assay for protein quantitation, including assay design strategies and reagents. In the most simple form of an elisa, antigens from the sample to be tested are attached to a surface.

03如何做出更好的 ELISA 实验? 想要做好一个 ELISA 实验,确保结果的准确性和可靠性,除了基本的实验步骤外,还需要注意一系列细节和考虑因素。

ELISA 利用抗原抗体特异性结合的原理,并通过酶联反应进行信号放大,经过一系列的孵育和洗涤步骤,最终实现对目标抗原或抗体的定量或定性检测。 酶联免疫吸附实验 (Enzyme linked immunosorbent assay,ELISA)是将 抗原 或 抗体 结合在 固相载体 表面,利用抗原抗体的特异性结合以及抗体或者抗原上标记的酶催化特定底物发生 显色反应,实现目标物检测的免疫分析方法,可测至皮摩尔(pmol)级别。 根據待測樣品與鍵結機制的不同,ELISA可設計出各種不同類型的檢測方式,主要以三明治法(sandwich)、間接法(indirect)、以及競爭法(competitive)三種為主。
