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)定大鼠血清,血漿及相關(guān)液體樣本中可溶性血管內(nèi)皮細(xì)胞蛋白C受體(sEPCR)含量。
實(shí)驗(yàn)原理:大鼠ELISA試劑盒說明書
本試劑盒應(yīng)用雙抗體夾心法測(cè)定標(biāo)本中大鼠可溶性血管內(nèi)皮細(xì)胞蛋白C受體(sEPCR)水平。用純化的大鼠可溶性血管內(nèi)皮細(xì)胞蛋白C受體(sEPCR)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可溶性血管內(nèi)皮細(xì)胞蛋白C受體(sEPCR),再與HRP標(biāo)記的可溶性血管內(nèi)皮細(xì)胞蛋白C受體(sEPCR)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可溶性血管內(nèi)皮細(xì)胞蛋白C受體(sEPCR)呈正相關(guān)。用酶標(biāo)儀在450nm波長下測(cè)定吸光度(OD值),通過標(biāo)準(zhǔn)曲線計(jì)算樣品中大鼠可溶性血管內(nèi)皮細(xì)胞蛋白C受體(sEPCR)濃度。

Rat soluble endothelial protein C receptor(sEPCR)
FOR RESEARCH USE ONLY |
Drug Names
Generic Name:Rat soluble endothelial protein C receptor(sEPCR)ELISA Kit.
Purpose
This kit allows for the determination of sEPCR concentrations in Rat serum, blood plasma, and other biological fluids.
Principle of the assay 大鼠ELISA試劑盒說明書
The kit assay Rat sEPCR level in the sample,use Purified Rat sEPCR antibody to coat microtiter plate wells, make solid-phase antibody, then add sEPCR to wells, Combined sEPCR 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 Rat sEPCR in the samples is then determined by comparing the O.D. of the samples to the standard curve.
