T7 RiboMAX™ Express RNAi System

The T7 RiboMAX™ Express RNAi System is an in vitro transcription system designed for producing milligram amounts of double-stranded RNA (dsRNA) in a short amount of time. The dsRNA is free of protein and other contaminants and is suitable for use in RNA interference (RNAi) in both mammalian and nonmammalian systems.

The T7 RiboMAX™ Express RNAi System can be used to synthesize short interfering RNAs (siRNAs) of 21bp for use in mammalian systems. siRNAs synthesized in vitro have been demonstrated to be as effective as chemically synthesized siRNAs for inducing RNAi in mammalian cells.

In addition, the T...
