This protocol outlines a new genetic complementation strategy to investigate gene function in Trypanosoma cruzi, the parasite causing Chagas disease. We combine CRISPR-Cas9 technology with recombination of variants of the target gene containing the desired mutations that are resistant to Cas9-cleavage, which enables detailed investigation of protein function. This experimental strategy overcomes some of the limitations associated with gene knockouts in T. cruzi. For complete details on the use and execution of this protocol, please refer to Marek et al. (2021).
