Preparation, Assembly, and Transduction of Transgenic Elements Using Mosaic Analysis with Dual Recombinases (MADR)

Abstract

Summary: This protocol focuses on the cloning and stable integration of sequences of interest by the use of a mosaic analysis with dual recombinases (MADR) plasmid that includes fusion proteins or independent proteins under the control of 2A peptide or IRES elements. Additionally, we describe how to generate a neural stem cell culture from Gt(ROSA)26Sortm4(ACTB-tdTomato, EGFP)Luo/J mice, and validate the MADR plasmids in vitro and in vivo by neonatal mouse brain electroporation. This protocol can be generalized to analyze any transgenic element using MADR technology.For complete details on the use and execution of this protocol, please refer to Kim et al. (2019).
