綿羊白細胞介素2 ELISA試劑盒
Sheep Interleukin 2(IL-2)ELISA Kit
實驗原理：本試劑盒用于測定綿羊血清，細胞上清及相關(guān)液體樣本中白細胞介素2（IL-2）的含量。應(yīng)用雙抗體夾心法測定標本中綿羊白細胞介素-2（IL-2）水平。用純化的綿羊白細胞介素-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胞介素-2，再與HRP標記的IL-2抗體結(jié)合，形成抗體-抗原-酶標抗體復(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白細胞介素-2（IL-2）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綿羊白細胞介素-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.
