This detailed volume focuses on genotyping and validation in addition to information on how to produce gene edited cells and animals for research. Future advances in biomedical research will benefit greatly from the use of precise gene targeting of transgenes in the genome as CRISPR technology supersedes earlier methods that relied on random transgene integration, which this collection reflects. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as tips for troubleshooting and avoiding known pitfalls.
