ELISA直接法和間接法優缺點
直接法(direct ELISA)將抗原直接固定在固相載體上,加入酶標記的一級抗體,即可測定抗原總量,此一級抗體的特異性非常重要。優勢:操作手續簡短,因無須使用二抗可避免交互反應。缺點:試驗中的一抗都得用酶標記,但不是每種抗體都適合做標記,費用相對提高。間接法(indirect ELISA)此測定方
ELISA分析缺點
ELISA實驗所有方法的缺點很明顯: 1、重復性不好; 2、收自身抗體、嗜異性抗體等干擾,易出現假陽性; 3、不論儀器和手工操作,干擾因素較多。影響最大的是溫度和時間。 1、直接法(direct ELISA) 將抗原直接固定在固相載體上,參加酶符號的一級抗體,即可測定抗原總量,此一級抗
