EDITGENE provides access to a comprehensive library of over 4,500 high-quality knockout (KO) cell lines, enabling researchers to save valuable time. Our custom gene knockout services are highly efficient, boasting a high positive rate while minimizing off-target effects. Clients also benefit from personalized, one-on-one support from a team of PhD experts from globally renowned institutions, ensuring top-tier service and results.

Researchers use KO cell lines to investigate gene functions by observing the effects of gene deletion on cellular behavior. This helps in understanding the role of genes in various processes like cell growth, metabolism, and signal transduction. KO cell lines are vital for studying diseases like cancer, genetic disorders, and neurodegenerative diseases.

Not all genes are suitable for knockout. Some gene knockouts may result in cell death or severe dysfunction, particularly for essential genes. In such cases, conditional knockouts or gene knockdowns (e.g., RNAi) may be used instead.

Gene knock-in plays a crucial role in drug development. It is used in target validation by introducing specific genes into cell lines or animal models to confirm drug target efficacy. It also aids in establishing disease models, testing drug efficacy and safety in these models, and supporting drug screening through high-throughput screening in knock-in cell lines to identify potential drug candidates. Additionally, gene knock-in helps uncover drug mechanisms, optimize drug structure, and improve dosing strategies, expediting drug development while enhancing efficacy and safety.

The main differences among Cas9, Cas12, and Cas13 lie in their action mechanisms:
· Cas12 is activated to cleave ssDNA trans-cleaving after binding with guide RNA and target DNA.
· Cas13 is activated to cleave ssRNA trans-cleaving after binding with guide RNA and target RNA.
· Cas9 has not been reported to exhibit trans-cleaving activity.

CRISPR libraries can be divided into whole-genome libraries and subgenomic libraries. If the goal is to perform screenings across the entire genome, a whole-genome library is the best choice. Such libraries typically contain sgRNAs targeting the entire genome. If the research focus is specific, such as targeting only particular gene families or specific signaling pathways, a subgenomic library can be chosen to reduce unnecessary screening workload and costs.

KO cell lines are used for in vitro experiments, suitable for high-throughput screening and cellular studies, while gene knockout animal models are used for in vivo experiments to study gene functions within an entire organism and its interaction with the environment.
