Abstract
Transgenesis, the process of incorporating an exogenous gene (transgene) into an organism’s genome, is a widely used tool to develop models of human diseases and to study the function and/or regulation of genes. Generating transgenic Xenopus is rapid and involves simple in vitro manipulations, taking advantage of the large size of the amphibian egg and external embryonic development. Restriction enzyme-mediated integration (REMI) has a number of advantages for transgenesis compared to other methods used to produce transgenic Xenopus, including relative efficiency, higher transgene expression levels, fewer genetic chimera in founder transgenic animals, and near-complete germ-line transgene transmission. This chapter explains the REMI method for generating transgenic Xenopus laevis tadpoles, including improvements developed to enable studies in the mature retina.
