Abstract
The CRISPR/Cas9 RNA-guided nuclease now enables a reverse genetics approach to investigate the function of genes of interest during regeneration in the axolotl. The process of generating the constructs necessary for targeting a gene of interest is considerably less labor intensive than for other methods of targeted mutagenesis such as Zinc finger nucleases or Transcription activator-like effector nucleases. Here, we describe the identification of targetable sequences in the gene of interest, the construction of unique guide RNAs, the microinjection of these RNAs with Cas9-encoding mRNA, the selection of well-injected animals, and an inexpensive, PCR-based method for identifying highly mutagenized animals.
