The mMESSAGE mMACHINE® High Yield Capped RNA Transcription Kits use Ambion's patented high yield transcription technology. Each reaction synthesizes 10-50 times the yield of capped RNA obtained with conventional in vitro transcription reactions.
The reaction is simple. DNA template is mixed with the reaction components and incubated at 37°C for up to 2 hours. Figure 1 shows a time course experiment that plots yield of a 3.7 kb capped transcript over time. With this template, the mMESSAGE mMACHINE reaction is complete in only 30 minutes. In addition to synthesizing high yields of capped RNA transcripts (Figure 1), mMESSAGE mMACHINE reactions also produce full-length transcripts. Figure 2 shows an Agilent bioanalyzer 2100 electropherogram of the 3.7 kb transcript. The presence of a single, strong peak indicates the predominance of full length transcript. This is also evident in Figure 3, in which mMESSAGE mMACHINE reactions producing 1.7 kb, 3.7 kb and 9 kb transcripts were analyzed on a conventional denaturing agarose gel.
We also offer the mMESSAGE mMACHINE T7 Ultra Kit for the generation of RNA transcripts capped with Anti Reverse Cap Analog (ARCA). A base modification in this cap analog generates RNAs with ARCA incorporated only in the functional, translatable orientation, resulting in higher protein yields. The mMESSAGE mMACHINE T7 Ultra Kit includes reagents for both transcription and the addition of a poly(A) tail to capped transcripts.
