A simple paintbrush technique nearly triples microinjection rates in Caenorhabditis elegans (C. elegans) genome engineering. This method enhances both speed and survival, making complex genetic modifications more accessible.

Area of Science:

  • Genetics and Genomics
  • Developmental Biology
  • Molecular Biology

Background:

  • Genome manipulation in *C. elegans* relies on microinjection, a technically demanding process.
  • Microinjection is a bottleneck for *C. elegans* genome engineering and transgenic approaches.
  • Advances in genetic methods have not been matched by improvements in microinjection techniques.

Approach:

  • Developed a simple, inexpensive method using a paintbrush for handling *C. elegans* during microinjection.
  • Compared microinjection rates and efficiency using the paintbrush method versus traditional handling.

Key Points:

  • The paintbrush method nearly tripled average microinjection rates.
  • Increased injection speed and post-injection survival rates, boosting overall throughput.
