Coronavirus: Research Guidance for the ChristianaCare Community >

Gene Editing Institute at ChristianaCare Health System’s Helen F. Graham Cancer Center & Research Institute, works directly in the design, optimization and application of CRISPR gene editing tools that can be used across a wide array of biomedical researches. With affordability in mind, the Institute provides customized CRISPR services with improved and streamlined CRISPR/Cas9 processes that allow timely delivery of high-quality clonal cell lines with knock-out or various knock-in mutations.
