Protocol for large DNA transgenesis in mice using the Cas9+Bxb1 toolbox.

Precise integration of DNA constructs greater than 3 kb into mouse zygotes is difficult. Here, we present a protocol for large DNA transgenesis in mice using the Cas9+Bxb1 toolbox. We describe steps for choosing mouse strains with preplaced attachment sites. We then detail procedures for microinjecting mouse zygotes with the plasmid donor DNA construct to generate transgenic mice by recombination-mediated cassette exchange. This protocol has the potential for application in exploring the functional implications of large structural variations in cancer. For complete details on the use and execution of this protocol, please refer to Low et al.1 and Hosur et al.2. Copyright © 2024 The Authors. Published by Elsevier Inc. All rights reserved.
