C. elegans Tagging via CRISPR Gene Editing
Tag your favorite gene at the native locus via CRISPR/Cas9 gene editing technology. Choose from a large selection of fluorescent proteins, immunotags and degron tags.
Custom tags and combinations (i.e. GFP::3xFLAG, etc.) are also available.

Process For Generating Strains
- Transgenic Design:
Design of donor homology plasmid, guide sgRNAs and choice of a selection cassette for expression of your fluorescently tagged gene.
- Molecular Assembly:
Confirm plasmids and construct high-quality components for genome editing.
- C. elegans Injections:
Using a plasmid-based DNA injection mix, our skilled injectionists perform microinjections with high survival and transgenesis rates.
- Candidate Screening:
Integration candidates are identified with the correct phenotype for the selection cassette. Confirm integration at the genomic level via PCR screening.
- Strain Confirmation:
PCR testing to confirm that the lines have the desired construct integration and sequencing to confirm that the integration occurred without error.
