BIOCHECK公司由創(chuàng)始人 Dr. John Chen, Medix創(chuàng)立, 是一家抓也提供腫瘤標(biāo)志物,心肌標(biāo)志物,激素類zui高性價比的抗體的公司。
簡要原理
利用競爭酶聯(lián)免疫方法,預(yù)先在微孔中包被羊抗兔抗體,實驗時先后加入氯霉素標(biāo)準品或待測樣本,氯霉素酶標(biāo)抗原和兔抗氯霉素抗體。經(jīng)過室溫溫育,反應(yīng)液中的兔抗氯霉素抗體與微孔板上的羊抗兔抗體結(jié)合,待測樣品中的抗原與氯霉素酶標(biāo)抗原競爭微孔板上的兔抗氯霉素抗體。洗滌后,沒有與抗
體結(jié)合的待測樣品中的抗原或酶標(biāo)抗原被洗去,再加入反應(yīng)底物,結(jié)合的酶標(biāo)抗原的酶將底物轉(zhuǎn)化為藍色產(chǎn)物,加入終止液后顏色由藍色變?yōu)辄S色。反應(yīng)完成后,樣品中氯霉素含量越多,反應(yīng)呈色就越淺;反之,樣品中氯霉素含量越少,則呈色越深。利用標(biāo)準曲線可計算出樣品中氯霉素含量。
