Design and Generation of Gene‐Targeting Vectors

This unit provides an overview of the major types of mutant alleles that can be generated by gene targeting in ES cells. It presents the growing public resources of premade gene targeting vectors, modified ES cells, and mutant mice. General guidelines for the design of targeting vectors are followed by protocols for the construction of vectors to generate knockout (KO), conditional KO, and subtle mutant alleles. Curr. Protoc.
