The new GENASSIST range of gene-editing kits and reagents enable easier, robust implementation of CRISPR and rAAV gene editing experiments. The current GENASSIST offering comprises both off-the-shelf reagents for using CRISPR editing technology and a unique kit combination of these reagents to allow customers to generate their own CRISPR-ready cell lines that constitutively express Cas9-nickase. Using such cell lines provides a quick start for customers, enabling them to make further modifications to the cell line more efficiently than if they were starting fresh each time. Horizon is also launching a new service for the design, manufacture and most importantly validation of CRISPR RNA guides, in order to maximize the likelihood that gene editing will occur as expected. The new GENASSIST kits, combined with access to rAAV, ZFN, and CRISPR technologies, give researchers an invaluable suite of tools to determine the function of endogenous gene alterations and their effect on disease and therapeutic responses.
