Introduction of Genome-wide Assembly and Annotation

A large-scale genetic loss-of-function experimental framework engineered to seek the equivalent of a few needles in a haystack is CRISPR screening. CRISPR screening makes it easier for a cell type to explore key genes or genetic sequences that induce a particular function or phenotype. CRISPR is a way of making double-strand cuts at directly aimed sites in DNA, as it is used by many scientists. When genomic DNA in cells produces such cuts, the cells utilize their DNA repair processes to fix the cuts. The repair method is typically imprecise, resulting in variations that throw the targeted gene out.

The CRISPR screen is an essential molecular target technique of high-throughput screening. An effective CRISPR screen begins with a well-designed library of sgRNA that targets the genes or loci of preference. Based on sequence and then synthesis, sgRNA is developed, accompanied by vector cloning or transcribed into RNA for cell system transfection. Then run a screen with a positive or negative selection that is widely utilized. Regarding physical segregation of cells into two or more communities, PCR amplification and hugely parallel sequencing will be carried out. The sgRNA and targeted genes of interest will be recognized after statistical analysis.

The Bioinformatics Analysis That We Can Provide

CD Genomics has established a cost-effective, efficient, and high-throughput tactic for CRISPR Screen sequencing by integrating amplicon-based next-generation sequencing to implement the growing demands of the scientific community. In order to assist people to evaluate gene functions in a high-throughput manner, our CRISPR Screen sequencing system can offer you direct and specific data about sgRNA and targeted gene analysis and functional enrichment assessment.

For high-throughput screening, CRISPR screen innovation can be utilized, a huge proportion of gene mutant cells can be produced, and the mutant cell library can be screened under the activation of various external conditions. It is possible to further define the connection between phenotype and genotype through high-throughput sequencing and bioinformatics evaluation. In addition, CRISPR/Cas9 library-based high-throughput screening also overwhelms the challenges of low transfection effectiveness and the capacity to inhibit gene expression only at the mRNA level faced by RNA interference screening innovation.  In the period of precision medicine, it has huge scientific clinical relevance and extensive application space.
