Our premium shRNA products use a microRNA-adapted shRNA design to promote more efficient cellular processing and reduce toxicity during RNAi experiments. Visit our shRNA applications page to learn more.

However, efficient gene silencing depends on both the shRNA design and expression level. Therefore, promoter selection is also critical to drive sufficient shRNA expression in your specific cell line.


SMARTvector™ – shRNA tailored to your experiment

SMARTvector customizable shRNA 

The SMARTvector backbone allows you to choose from seven promoters and three reporter options to optimize shRNA for your specific cells and experimental requirements.

Designed using our most advanced microRNA-based shRNA-specific rational design algorithm, SMARTvector lentiviral shRNA expressed under an optimized promoter produces highly potent and specific silencing. Identify the optimal promoter for your cell line with the SMARTchoice promoter selection plate.

SMARTvector shRNA are also available with a Tet-on® 3G inducible promoter for reversible, controlled gene silencing, which is especially useful when studying the function of essential genes.


GIPZ/TRIPZ collections

GIPZ shRNA and TRIPZ inducible shRNA offer specific gene silencing with minimized cellular toxicity, but lack the SMARTvector's promoter/reporter flexibility. Both GIPZ and TRIPZ collections were developed in collaboration with Gregory Hannon (Cold Spring Harbor Laboratories) and Steve Elledge (Harvard).
