title: Microinjection of in vitro transcribed RNA and antisense oligonucleotides in mouse oocytes and early embryos to study the gain- and loss-of-function of genes.
abstract: Mouse oocytes have proven useful in experiments aimed at studying gene function. They have been used to analyze the gain-of-function acquired after microinjection of RNA transcribed in vitro from specific gene constructs, and for establishing loss-of-function mutation obtained by injecting in vitro transcribed antisense RNA and/or synthetic oligonucleotides. This article presents protocols utilized in these studies. Specifically, the acquisition of mouse oocytes and/or embryos, the genesis of the necessary DNA and/or RNA to be used, and procedures for microinjection.
