161次小鼠乙醛脫氫酶(ALDH)酶聯(lián)免疫分析(ELISA)
試劑盒使用說明書
本試劑僅供研究使用 目的:本試劑盒用于測(cè)定小鼠血清,組織及相關(guān)液體樣本中乙醛脫氫酶(ALDH)的含量。
實(shí)驗(yàn)原理:
本試劑盒應(yīng)用雙抗體夾心法測(cè)定標(biāo)本中小鼠乙醛脫氫酶(ALDH)水平。用純化的小鼠乙醛脫氫酶(ALDH)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乙醛脫氫酶(ALDH),再與HRP標(biāo)記的乙醛脫氫酶(ALDH)抗體結(jié)合,形成抗體-抗原-酶標(biāo)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(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乙醛脫氫酶(ALDH)呈正相關(guān)。用酶標(biāo)儀在450nm波長(zhǎng)下測(cè)定吸光度(OD值),通過標(biāo)準(zhǔn)曲線計(jì)算樣品中小鼠乙醛脫氫酶(ALDH)濃度。

Drug Names
Generic Name:Mouse aldehyde dehydrogenase (ALDH) ELISA Kit.
Purpose
This kit allows for the determination of ALDH concentrations in Mouse serum, tissue, and other biological fluids.
Principle of the assay
The kit assay Mouse ALDH level in the sample,use Purified Mouse ALDH antibody to coat microtiter plate wells, make solid-phase antibody, then add ALDH to wells, Combined ALDH antibody 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 ALDH in the samples is then determined by comparing the O.D. of the samples to the standard curve.

6.add enzyme:Add HRP-Conjugate reagent 50μl to each well, except blank well.
7.incubate:Operation with 3.
8.washing:Operation with 5.
9.color:Add Chromogen Solution A 50ul and Chromogen Solution B to each well, evade the light preservation for 15 min at 37℃
10.Stop the reaction:Add Stop Solution50μl to each well, Stop the reaction(the blue color change to yellow color).
