产品描述（Product Details）
T7 RNA Polymerase is a DNA-dependent RNA polymerase with strict specificity for the T7 phage promoter. The enzyme is widely used for the synthesis of specific transcripts from DNA in the 5'→ 3' direction, as well as being a suitable model for studying the mechanisms of transcription. The RNA produced by T7 RNA Polymerase is suitable for many downstream applications.
应用说明（Application）
- Synthesis of the single-strand RNA
- Synthesis of highly labeled RNA probes
- Synthesis of precursors of siRNA
- Synthesis of precursors for RNA splicing reactions
- Synthesis of capped mRNA when a cap analog is used as a primer
