Overview
Knockout Cell Lines for Functional Studies
Knockout (KO) cell lines are essential tools for gene function studies, disease modeling, and drug discovery. However, generating reliable KO models can be challenging, with risks of incomplete knockouts, long timelines, and low editing efficiency. Many researchers spend months on KO cell line development, only to face residual protein expression or unsuccessful edits.

Cyagen’s Cell iGeneEditor™ technology overcomes these challenges with high-efficiency gene disruption, rapid turnaround, and customizable deliverables. Our optimized workflow ensures complete target gene knockout, delivering high-quality cell models in as little as 4 weeks.
Explore Ready-to-Use Mouse Models
Discover over 18,000 validated mouse strains—including knockout, conditional knockout, and humanized models—covering 20+ research areas such as oncology, neurology, and metabolism. All models are supported by detailed genotype data and guaranteed quality, helping you fast-track discovery with confidence.
