產(chǎn)品說(shuō)明
Cell Counting Kit-8 簡(jiǎn)稱CCK-8 試劑盒，為MTT 法的替代方法，是一種基于WST（水溶性四唑鹽，化學(xué)名2-(2-甲氧基-4-硝苯基)-3-(4-硝苯基)-5-(2,4-二磺基苯)-2H-四唑單鈉鹽）的廣泛應(yīng)用于細(xì)胞增殖和細(xì)胞毒性的快速高靈敏度檢測(cè)試劑盒?？捎糜谒幬锖Y選、細(xì)胞增殖測(cè)定、細(xì)胞毒性測(cè)定、腫瘤藥敏等試驗(yàn)。
CCK-8細(xì)胞增殖及毒性檢測(cè)試劑盒使用說(shuō)明：
一、制作標(biāo)準(zhǔn)曲線（測(cè)定細(xì)胞具體數(shù)量時(shí)）
1、先用細(xì)胞計(jì)數(shù)板計(jì)數(shù)所制備的細(xì)胞懸液中的細(xì)胞數(shù)量，然后接種細(xì)胞。
2、按比例依次用培養(yǎng)基等比稀釋成一個(gè)細(xì)胞濃度梯度，一般要做3-5 個(gè)細(xì)胞濃度梯度，每組3-6 個(gè)復(fù)孔。
3、接種后培養(yǎng)至細(xì)胞貼壁，然后加CCK-8 試劑培養(yǎng)一定時(shí)間后測(cè)定OD 值，制作出一條以細(xì)胞數(shù)量為橫坐標(biāo)（X 軸），OD 值為縱坐標(biāo)（Y 軸）的標(biāo)準(zhǔn)曲線。根據(jù)此標(biāo)準(zhǔn)曲線可以測(cè)定出未知樣品的細(xì)胞數(shù)量（試用此標(biāo)準(zhǔn)曲線的前提是實(shí)驗(yàn)的條件要一致，便于確定細(xì)胞的接種數(shù)量以及加入CCK-8 后的培養(yǎng)時(shí)間。）
CCK-8細(xì)胞增殖及毒性檢測(cè)試劑盒二、細(xì)胞活性檢測(cè)
1、在96 孔板中接種細(xì)胞懸液（100μL/孔）。將培養(yǎng)板放在培養(yǎng)箱中預(yù)培養(yǎng)（在37℃,5% CO2 的條件下）。
2、向每孔加入10μL CCK-8 溶液（注意不要在孔中生成氣泡，它們會(huì)影響OD 值的讀數(shù)）。
3、將培養(yǎng)板在培養(yǎng)箱內(nèi)孵育1-4 小時(shí)。
4、用酶標(biāo)儀測(cè)定在450nm 處的吸光度。
5、如果暫時(shí)不測(cè)定OD 值，打算以后測(cè)定的話，可以向每孔中加入10μL 0.1M 的HCl 或者1%SDS(W/V)溶液，并遮蓋培養(yǎng)板避光保存在室溫條件下。在24 小時(shí)內(nèi)吸光度不會(huì)發(fā)生變化。
