綿羊白細(xì)胞介素2 ELISA試劑盒 Sheep Interleukin 2(IL-2)ELISA Kit 實(shí)驗(yàn)原理:本試劑盒用于測(cè)定綿羊血清,細(xì)胞上清及相關(guān)液體樣本中白細(xì)胞介素2(IL-2)的含量。應(yīng)用雙抗體夾心法測(cè)定標(biāo)本中綿羊白細(xì)胞介素-2(IL-2)水平。用純化的綿羊白細(xì)胞介素-2(IL-2)抗體包被微孔板,制成固相抗體,往包被單抗的微孔中依次加入白細(xì)胞介素-2,再與HRP標(biāo)記的IL-2抗體結(jié)合,形成抗體-抗原-酶標(biāo)抗體復(fù)合物,經(jīng)過(guò)*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉(zhuǎn)化成藍(lán)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白細(xì)胞介素-2(IL-2)呈正相關(guān)。用酶標(biāo)儀在450nm波長(zhǎng)下測(cè)定吸光度(OD值),通過(guò)標(biāo)準(zhǔn)曲線計(jì)算樣品中綿羊白細(xì)胞介素-2(IL-2)濃度。 Principle of the assay This kit allows for the determination of IL-2 concentrations in Sheep serum, cell culture supernatant and other biological fluids.The kit assay Sheep IL-2 level in the sample,use Purified Sheep IL-2 antibody to coat microtiter plate wells, make solid-phase antibody, then add IL-2 to wells, Combined IL-2antibody which With HRP labeled, become antibody - antigen - enzyme-antibody 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 IL-2 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
