Improved Lentiviral Vectors And Genome Wide Libraries For Crispr Screening

Crispr gene editing is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified.

Improved lentiviral vectors and genome wide libraries for crispr screening. Genome wide targeted loss of function pooled screens using the crispr clustered regularly interspaced short palindrome repeatsassociated nuclease cas9 in human and mouse cells provide an alternative screening system to rna interference rnai and have been used to reveal new mechanisms in diverse biological models 14previously we used a genome scale crispr knock out gecko. Improved vectors and genome wide libraries. The approach utilises the crispr cas9 gene editing system coupled with libraries of single guide rnas which are designed to target every gene in the genome. 2mcgovern institute for brain research massachusetts institute of technology cambridge ma 02139 usa.

Genome wide crispr cas9 knockout screens aim to elucidate the relationship between genotype and phenotype by ablating gene expression on a genome wide scale and studying the resulting phenotypic alterations. Lentivirus production of the pooled library infection of the opascas12a transduced rn2 cells and the screening itself were carried out as in the single gene knockout screening described above. These new lenticrispr vectors and human and mouse libraries further improve the gecko reagents for diverse screening applications. Another approach to crispr screening includes using two different targeting sequences per lentivirus within a library an approach that has a variety of applications ranging from use of cas9 nickases in screening to deletion of numerous large segments of genomic dna in large screening projects.
