DegeneratePCR,ashortguide.
What is degenerate PCR? Degenerate PCR is in most respect identical to ordinary PCR, but with one major difference. Instead of using specific PCR primers with a given sequence, you use mixed PCR primers. That is, if you do not know exactly the sequence of the gene you are going to amplify, you insert "wobbles" in the PCR primers where there is more than one possibility. For instance if you ......閱讀全文

遞減聚合酶鏈式反應的簡介
遞減PCR,亦稱降落PCR(touchdown PCR)是一種PCR(聚合酶鏈式反應)方法,用來避免非特異性序列的擴增。PCR中引物的黏合溫度(annealing temperature)決定了黏合的特異性,溫度越高特異性越強,但過高則不能實現引物和模板的結合,而過低會產生大量非特異性產物。因此

TAILPCR(thermal-asymmetric-interlaced-PCR)簡介
在分子生物學研究中,基因克隆和分子雜交的探針制備等操作常需分離與已知DNA序列鄰近的未知序列,TAIL-PCR又叫熱不對稱交錯PCR,能夠較好地解決上述難題。該技術通過3個嵌套的特異性引物分別和簡并引物組合進行連續的PCR循環,利用不同的退火溫度選擇性地擴增目標片段,所獲得的片段可以直接用做探針標記
常規雜交反應存在的問題
常規雜交反應由于受到探針解鏈溫度、溶液中靶序列的初始濃度及探針長度的影響。樣品中不同探針所對應的靶序列的拷貝數不盡相同,探針的解鏈溫度也難以保持一致,這樣不同位點的雜交速度并不完全與各自靶序列的拷貝數成正比,檢測結果也就不具有良好的平行性。所以必需選擇最理想的條件以盡可能使正確配對的序列不被遺漏

1、簡介?重疊PCR也是基本的PCR原理:變性-退火-延伸。不同的是在重疊PCR過程是兩個或者幾個片段重疊延伸之后,再進行指數擴增的PCR過程。 ?2、基本原理*步:PCR產生兩個或者幾個片段,這幾個片段之間必須有重疊區。?第二步:以兩個片段為例,見上圖,*步產生的兩個片段,A D鏈之間有互補,B
普通PCR梯度PCR-原位PCR-熒光定量PCR儀的區別
