如何分析 qPCR 數據 透過測量並定量報告分子所發出的螢光;這些報告分子通常是能插入雙股 DNA 鹼基之間的染料(例如 SYBR® Green、溴化乙銨),或是專門設計用以結合 DNA 上特定序列的探針(例如 分子信標、TaqMan® 探針)。 ## qPCR 數據的相對定量 qPCR 數據主要有兩種定量方法。相對定量是較常見的方法,其利用 ΔΔCt 資訊,透過與對照基因比較,來確定樣本中目標基因的表達量或豐度比,並以參考基因的表達比進行歸一化。由於目標基因與參考基因的效率 E 值不同,此方法亦會考量 E 值之間的差異。此方法在基因表達分析中較為常用。 ## qPCR 數據的絕對定量 第二種方法——絕對定量——在環境微生物學中較為常見,並採用標準曲線(SC)法。 標準曲線法利用已知模板濃度 N0 的稀釋系列,透過 log(N0) 與 CT(閾值週期)的線性回歸來建立標準曲線。隨後利用此曲線計算樣本的模板濃度。此方法的基礎在於假設樣本的效率值與標準品的效率值相同。  [瀏覽所有 qPCR 產品](https://www.sigmaaldrich.com/search/facet-search?focus=products&page=1&perpage=30&sort=relevance&term=facet-search&type=product) [![文件搜尋](https://www.sigmaaldrich.com/content/dam/cms-commons/sigmaaldrich/marketing/global/images/ecommerce/document-search.png "文件搜尋")](https://www.sigmaaldrich.com/documents-search) ### [想了解更多具體資訊嗎?](https://www.sigmaaldrich.com/documents-search) 請造訪我們的文件搜尋頁面,查閱產品資料表、認證書及技術文件。 [搜尋文件](https://www.sigmaaldrich.com/documents-search) ##
