PCR的原理
聚合酶鏈式反應簡稱PCR（英文全稱：Polymerase Chain Reaction）， 聚合酶鏈式反應簡稱PCR。聚合酶鏈式反應，其英文Polymerase Chain Reaction(PCR)是體外酶促合成特異DNA片段的一種方法,由高溫變性、低溫退火（復性）及適溫延伸等幾步反應組成一個周期
沙眼衣原體實驗診斷技術進展
1907年，捷克學者Halberstaeder和Prowazek發現沙眼包涵體，1956年我國學者湯飛凡等分離沙眼衣原體成功，引起了全世界對其進行廣泛深入的研究［1］。沙眼衣原體(chlamydia trachomatis, Ct)與人類疾病關系密切，且目前已成為許多國家和地區常見的性傳播疾

DNA連接酶的用途
聚合酶鏈反應(polymerase chain reaction, PCR)。Taq酶擴增的PCR產物，3’末端總是帶有1個非模板依賴型的突出堿基，而這個堿基幾乎總是A，因為Taq酶對dATP具有優先聚合活性，故可用T載體克隆。
