ELISA法
ELISA法是建立在抗原與抗體免疫學反應的基礎上，因而，具有特異性。由于測定中需要酶標記抗原或抗體，酶分子與抗原或抗體分子的結合物可以催化底物分子發生反應，產生放大作用，正因為此種放大作用而使本法具有很高的敏感性。常用的ELISA分析1)?? 測定抗原A??將抗體吸附于固相表面，這個過程叫包被。B
ELISA實驗
酶聯免疫吸附實驗（ELISA）可以用于：（1）檢測大分子抗原和特異性抗體等；（2）具有快速、靈敏、簡便、載體易于標準化等優點。實驗方法原理ELISA的基礎是抗原或抗體的固相化及抗原或抗體的酶標記。結合在固相載體表面的抗原或抗體仍保持其免疫學活性，酶標記的抗原或抗體既保留其免疫學活性，又保留酶的活性。

ELISA原理
實驗原理ELISA是以免疫學反應為基礎，將抗原、牽9體的特異性反應與酶對底物的催化作用相結合起來的一種敏感性很高的試驗技術。由于抗原、抗體的反應在一種固相載體──聚苯乙烯微量滴定板的孔中進行，每加入一種試劑孵育后，可通過洗滌除去多余的游離反應物，從而保證試驗結果的特異性與穩定性。在實際應用中，通過不
