人抗心磷脂抗體IgA(ACA-IgA)ELISA試劑盒 Generic Name:Human ACA-IgA ELISA Kit 實驗原理: 本試劑盒用于測定人血清,血漿及相關(guān)液體樣本中抗心磷脂抗體IgA(ACA-IgA)的含量。應(yīng)用雙抗原夾心法測定標本中人抗心磷脂抗體IgA(ACA-IgA)水平。用純化的抗心磷脂抗體IgA(ACA-IgA)抗原包被微孔板,制成固相抗原,往包被抗原的微孔中依次加入ACA-IgA,再與HRP標記的抗心磷脂抗體IgA(ACA-IgA)抗原結(jié)合,形成抗原-抗體-酶標抗原復(fù)合物,經(jīng)過*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉(zhuǎn)化成藍色,并在酸的作用下轉(zhuǎn)化成zui終的黃色。顏色的深淺和樣品中的抗心磷脂抗體IgA(ACA-IgA)抗體呈正相關(guān)。用酶標儀在450nm波長下測定吸光度(OD值),通過標準曲線計算樣品中人抗心磷脂抗體IgA(ACA-IgA)濃度。 Principle of the assay The kit assay Human ACA-IgA level in the sample,use Purified Human ACA-IgA antigen to coat microtiter plate wells, make solid-phase antigen, then add ACA-IgA to wells, Combined ACA-IgA antigen which With HRP labeled ,become antigen –antibody - enzyme- antigen complex, after washing Compley, Add TMB substrate solution,TMB substrate becomes blue color At HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of ACA-IgA in the samples is then determined by comparing the O.D. of the samples to the standard curve. 上海華壹生物科技有限公司 Shanghai HuaYi Bio-technology Co.,Ltd
