제품 설명
High Yield RNA Synthesis Kit for Co-transcription (low dsRNA, with LZCap AG)
제품 번호
10635ES
제품 설명
The kit utilizes T7 RNA Polymerase (Low dsRNA) and high-affinity LZcap AG Cap1 analog to produce mRNAs with significantly reduced double-stranded RNA (dsRNA) content and enhanced expression. Single-stranded RNAs are synthesized using linear double-stranded DNA containing a T7 promoter sequence as the template. Modified nucleotides, such as biotin or dye-labeled nucleotides, can be incorporated during transcription to generate labeled RNA. The kit supports the synthesis of both long and short transcripts, yielding 100–200 μg of RNA from 1 μg of DNA template. Substituting UTP with N1-Me-Pseudo UTP reduces RNA immunogenicity. The resulting RNA is suitable for downstream applications, including RNA structure and function studies, RNase protection, probe hybridization, RNAi, microinjection, and in vitro translation.
This product should be stored at -25 ~-15℃ for one year.
