shRNA clones can be propagated as needed
The RNAi Consortium shRNA clone libraries will comprise a comprehensive collection of 150,000 pre-cloned lentiviral-based shRNA vector constructs targeting 15,000 human genes and 15,000 mouse genes
Sigma-Aldrich has introduced the Mission RNAi product line, including the first available formats for the RNAi Consortium (TRC) shRNA libraries The Mission TRC shRNA clone libraries will comprise a comprehensive collection of 150,000 pre-cloned lentiviral-based shRNA vector constructs targeting 15,000 human genes (Mission TRC-Hs1.0) and 15,000 mouse genes (Mission TRC-Mm1.0)

Expanding shRNA libraries of the RNAi Consortium
Sigma-Aldrich announces the newest release of the Mission TRC shRNA human and mouse libraries for RNA interference (RNAi)-based research
Design and development of the TRC libraries is being led by the Broad Institute of the Massachusetts Institute of Technology (MIT) and Harvard University.
Sigma-Aldrich recently entered into an agreement with MIT to serve as a scientific collaborator and distribution partner of TRC, which is comprised of seven world-class academic research institutions and four commercial life science research partners.
To date, the collection includes approximately 35,000 shRNA vector constructs targeting 5300 human genes and 2200 mouse genes.
The libraries will be expanded on a quarterly basis to include new gene targets.
Each target is currently represented by an average of 3-5 shRNA vectors supplied individually in frozen bacterial glycerol stock format.
Compared to existing synthetic siRNAs, the Mission shRNA clones will provide a renewable resource that can be propagated as needed.
Upon transfection of the purified plasmid DNA, transient or stable gene silencing may be achieved depending upon the desired duration of phenotypic observation.
In addition, the clones may be combined with lentiviral packaging systems for infection and integration into the genomes of traditionally difficult cell lines such as primary cells and non-dividing cells.
"The lentiviral-based system provides several advantages over other available viral methods including broad tropism, receptor-independent delivery, and the ability to integrate into the genome without a mitotic event," commented Keith Jolliff, global marketing manager of molecular biology at Sigma-Aldrich.
"The Mission TRC collection is the first comprehensive lentiviral-based pre-cloned shRNA library, and we plan to facilitate its use by researchers worldwide for advancement of functional genomics research.".
