實時定量PCR（RealtimequantitativePCR）
mRNA表達的研究 微小殘留病變的檢測 腫瘤耐藥基因表達的研究 病毒感染的定量監測Vs普通PCR，RT-PCR的優勢 采用封閉的檢測模式，因此擴增產物導致污染的可能性比普通PCR要小得多 。 擴增產物的檢測在PCR擴增過程中同時進行，并且數據的采集、分析全部由 儀器 自動完成，因此整個檢測所 需的時間比普通PCR要節省許多。 檢測模式功能強大，具備定性、定量、突變、多項目等檢測功能。而普通PCR要完成上述項目需采用不同的技術平臺。 進行定量檢測時，其定量線性范圍（5-6 logs）比普通PCR（2-3 logs）要寬得多。 Real-time定量PCR儀是在普通PCR 儀的基礎上再配備一個激發光源和熒光信號檢測系統的裝置。通過PCR反應的數學函數關系，加入標準品，可以對待測樣品中的目標基因進行準確定量。Real-Time PCR 熱循環儀（PCR儀）熒光檢測系統計算機及軟件系統......閱讀全文

實時熒光定量PCR（Quantitative－Realtime－PCR－，qPCR）技術介紹
熒光定量PCR也叫Real-Time PCR，是美國PE（Perkin Elmer）公司1995年研制出來的一種新的核酸定量技術。熒光定量PCR的發展史是一部ABI、羅氏和伯樂等巨頭的蕩氣回腸的斗爭史，感興趣的可以去查查。該技術是目前最成熟，使用最廣泛的半定量PCR技術。? ??熒光染料法（SYBR
