样品材料
样品材料
- 线性化质粒DNA:待转录的DNA将会被克隆至含有SP6,T7或T3 RNA聚合酶启动子并相邻于多接头的合适转录载体的多接头位点。对于′流失′转录本的合成,质粒是通过限制性酶进行线性化的。应使用限制性酶生成的5′-突出;应避免3′突出。线性化模板DNA应采用酚氯仿萃取和乙醇沉淀法纯化,以避免RNase污染。为′完成′转录,使用了环状质粒DNA
- PCR产物:含有RNA聚合酶启动子序列的PCR片段,也可以作为转录模板。推荐在转录前通过凝胶电泳纯化正确的PCR片段。
- 标记效率:μ通过1μg线性模板DNA和RNA聚合酶进行标准标记反应,产生大约10μg全长生物素标记RNA。在斑点试验中,联用抗生物素-AP与化学发光底物CSPD可检测低至0.3pg的生物素标记RNA。
