Abstract

Introducing exogenous DNA into an embryo can promote misexpression of a gene of interest via transcription regulated by an attached enhancer-promoter. This protocol describes plasmid DNA microinjection into Xenopus embryos for misexpression of genes after zygotic gene expression begins. It also describes a method for coinjecting a reporter plasmid with mRNA or antisense morpholinos to perform luciferase reporter assays, which are useful for quantitative analysis of cis-regulatory sequences responding to endogenous or exogenous stimuli in embryos.
