原理:ELISA是以免疫學(xué)反應(yīng)為基礎(chǔ),將抗原、抗體的特異性反應(yīng)與酶對(duì)底物的高效催化作用相結(jié)合起來(lái)的一種敏感性很高的試驗(yàn)技術(shù)。由于抗原、抗體的反應(yīng)在一種固相載體──聚苯乙烯微量滴定板的孔中進(jìn)行,每加入一種試劑孵育后,可通過(guò)洗滌除去多余的游離反應(yīng)物,從而保證試驗(yàn)結(jié)果的特異性與穩(wěn)定性。在實(shí)際應(yīng)用中,通過(guò)不同的設(shè)計(jì),具體的方法步驟可有多種。即:用于檢測(cè)抗體的間接法(圖a)、用于檢測(cè)抗原的雙抗體夾心法(圖b)以及用于檢測(cè)小分子抗原或半抗原的抗原競(jìng)爭(zhēng)法等等。比較常用的是ELISA雙抗體夾心法及ELISA間接法。

elisa試劑盒:Elisa生物試驗(yàn)是一種敏感性高,特異性強(qiáng),重復(fù)性好的實(shí)驗(yàn)診斷方法。由于其試劑穩(wěn)定、易保存,操作簡(jiǎn)便,結(jié)果判斷較客觀等因素,已廣泛應(yīng)用在免疫學(xué)檢驗(yàn)的各領(lǐng)域中。ELISA檢測(cè)試劑盒是用于體外定性檢測(cè)人血清或血漿中的抗人類戊型肝炎(HEV)病毒 IgM 抗體ELISA檢測(cè)。B403 蘋果酸酶(ME)試劑盒 紫外分光光度法 50管/48樣

Principle: ELISA is a highly sensitive immunological reaction test based technique, the antigen, the antibody specifically reacts with the enzyme substrate for efficient catalysis combined together. Since the antigen antibody reaction in a solid phase carrier ─ ─ polystyrene microtiter plate wells conducted after each addition of a reagent incubation, the excess can be removed by washing the free reactants to ensure the specificity of the test results and stability. In practice, the different design of specific process steps can have many. Namely: the indirect method for the detection of antibodies (Figure a), for the detection of antigen double antibody sandwich method (Figure b) and small molecules for the detection of antigen or hapten antigen competition law, and so on. More common is the double antibody sandwich ELISA and indirect ELISA.
