siRNADesignGuidelines
Using siRNA for gene silencing is a rapidly evolving tool in molecular biology. There are several methods for preparing siRNA, such as chemical synthesis, in vitro transcription, siRNA expression vectors, and PCR expression cassettes. Irrespective of which method one uses, the first step in designing a siRNA is to choose the siRNA target site. The guidelines below for choosing siRNA target sites are based on both the......閱讀全文

siRNA表達框架制備siRNA的方法介紹
siRNA表達框架（siRNA expression cassettes，SECs）是一種由PCR得到的siRNA表達模版，包括一個RNA pol Ⅲ啟動子，一段發夾結構siRNA，一個RNA pol Ⅲ終止位點，能夠直接導入細胞進行表達而無需事前克隆到載體中。和siRNA表達載體不同的是，SECs

引物設計（Primer－Design）的原則
首先引物要跟模板緊密結合，其次引物與引物之間不能有穩定的二聚體或發夾結構存在，再次引物不能在別的非目的位點引起DNA聚合反應（即錯配）。圍繞這幾條基本原則，設計引物需要考慮諸多因素，如引物長度（primer length）、產物長度（product length）、序列Tm值（melting t
siRNA表達載體制備siRNA的方法介紹
多數的siRNA表達載體依賴三種RNA聚合酶Ⅲ啟動子（pol Ⅲ）中的一種，操縱一段小的發夾RNA（short hairpin RNA，shRNA）在哺乳動物細胞中的表達。這三類啟動子包括大家熟悉的人源和鼠源的U6啟動子和人H1啟動子。之所以采用RNA pol Ⅲ啟動子是由于它可以在哺乳動物細胞中表

siRNA表達框架(siRNA expression cassettes，SECs)是一種由PCR得到的siRNA表達模版，能夠直接導入細胞進行表達而無需事前克隆到載體中。這個方法最早是由Castanotto和其同事采用，包括一個RNA polⅢ啟動子，一段發夾結構siRNA，一個RNA pol I
siRNA制備方法
體外制備1.化學合成許多國外公司都可以根據用戶要求提供高質量的化學合成siRNA。主要的缺點包括價格高，定制周期長，特別是有特殊需求的。由于價格比其他方法高，為一個基因合成3―4對siRNAs 的成本就更高了，比較常見的做法是用其他方法篩選出最有效的序列再進行化學合成。最適用于：已經找到最有效的si
