CELLECTA, INC. SBIR Grant Work Finds Way to Increase CRISPR Effectiveness for Genetic Screens
April 12, 2016 (PRNewswire)
Cellecta, Inc. developed an approach that improves CRISPR single-guide RNA (sgRNA) designs with the successful completion of its NIH Phase I SBIR grant “CRISPR/Cas9 Genome-Wide sgRNA Library Screening Platform.” The results move forward Cellecta’s goal of developing a library of validated CRISPR guide RNA sequences that can be used to improve the efficiency of CRISPR genome-wide genetic knockout screens.
Dr. Donato Tedesco, senior scientist at Cellecta and the lead scientist on this study expressed his excitement about the findings by noting that, “The results of this work are actually very practically useful since they provide an approach to improve the effectiveness of any sgRNA regardless of the gene it targets. A few modifications of the constant region of the sgRNA produce a marked increase in the rate of CRISPR-mediated gene knockout and significantly increase the strength of the data signal in a genetic screen.”

CELLECTA, INC. Announces Launch of Human Whole Genome CRISPR Knockout Library
July 31, 2015 (PRNewswire)
Cellecta announced the release of its pooled CRISPR Guide RNA (sgRNA or gRNA) Knockout Library targeting nearly all human protein coding genes. This makes it the first company to produce a lentiviral based CRISPR library that targets nearly all of the almost 20,000 protein encoding genes in the human genome. The CRISPR Human Genome Knockout Library, as it is called, was designed as three modules each targeting approximately a third of the human genome with eight sgRNAs per gene, which is a higher number than most other libraries use. In addition, the sgRNAs in Cellecta’s library incorporate improved design features that increase their effectiveness and they have been filtered to ensure they are unique for each gene target to minimize false positive results.  Download PDF>

This resource will provide a powerful tool for researchers to identify, in a single experiment, the genes that are important for cell growth, drug effectiveness, or other biological responses and has wide implications in the discovery of novel drug targets and identifying drug mechanisms.

CELLECTA, INC. Receives Second Phase Contract from the National Cancer Institute (NCI) to Identify Lethal Gene Combinations in Cancer Cell Models
October 23, 2012 (PRWeb)
Cellecta received a Phase II SBIR contract from the National Cancer Institute to identify combinations of DNA damage and repair genes that are essential for cancer cells. There is great interest in these lethal gene combinations for drug development since therapies targeting multiple genes simultaneously can be much more effective at minimizing acquired resistance to a treatment over time. However, identification of these pairs is problematic using standard serial assays. Cellecta’s pooled RNAi screening solves this problem.
