Gene editing

Understand disease mechanisms at the genomic level


Gene editing refers to the process of changing regions of cellular DNA. The most common gene editing techniques involve inactivating a gene’s function (knockout), introducing or correcting a SNP mutation, or adding a reporter tag to an endogenous gene (knock-in). These changes are permanent and heritable, resulting in a newly engineered cell line.
With our Edit-R™ CRISPR-Cas9 reagents, researchers can make targeted, specific edits to any gene in practically any cell type. Additionally, Horizon offers a wide selection of pre-made edited cell lines and expert genome engineering services.
