SP6 RNA Polymerase is used for the synthesis of RNA transcripts in the 5´→ 3´ direction from vectors containing the SP6 phage promoter, while T7 RNA Polymerase catalyzes the synthesis of RNA in the presence of a …
WebT7和SP6 RNA聚合酶还会在完成模板编码的转录产物合成后继续在其3'端添加1-3 nt任意碱基，造成产物3'端异质[13]。 不同的转录模型形成的初始转录物不同，线性转录模型产生的是模板编码的RNA产物单体；滚环模型产生的是模板编码的RNA首尾串联而成的聚合物。 WebT7 RNA Polymerase is a DNA-dependant RNA Polymerase that exhibits a very high specificity for the T7 promoter sequence. The polymerase is useful for synthesizing large amounts of RNA suitable for in vitro translation and anti-sense RNA research. It can also produce highly sensitive radiolabeled RNA transcripts suitable for hybridization probes.
