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

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
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

普通PCR梯度PCR-原位PCR-熒光定量PCR儀的區別
普通PCR儀: 一般把一次PCR擴增只能運行一個特定退火溫度的PCR儀,稱之為普通PCR儀,也就是傳統的PCR儀。如果要用它做不同的退火溫度則需要多次運行。如;(ABI 2720) 梯度PCR儀: 一次性PCR擴增可以設置一系列不同的退火溫度條件(通常12種溫度梯度)的稱
PCR各處應用模式
?一、兼并引物(Degenerate primer)PCR密碼子具有兼并性,如表22-4,單以氨基酸順序推測編碼的DNA序列是不精確的,但可以設計成對兼并引物,擴增所有編碼已知順序的核酸序列。用兼并引物時寡核苷酸中核苷酸序列可以改變,但核苷酸的數量應相同。兼并度越低,產物特異性越強,設計引物時應盡量
