C. elegans Gene Knockin by CRISPR/Cas9

The emergence of CRISPR/Cas9-based gene editing technology has revolutionized biological science research and is rapidly becoming an indispensable experimental tool for researchers of genetic model organisms such as C. elegans. CRISPR/Cas9 can insert DNA fragments into the C. elegans genome for efficient targeted genome editing. Our C. elegans gene knockin services include tagging service and point mutation service.

Applications of CRISPR/Cas9 Knockin

As a valuable tool for a variety of biomedical research applications, CRISPR/Cas9 offers a wide range of possibilities for customizing various models of C. elegans and thus advancing scientific research.

  • Gene Function Studies: CRISPR/Cas9 knockin technology is a powerful tool for studying genetic interactions and complexity, allowing researchers to introduce mutations, reporter genes or functional progenitors into specific genomic loci in C. elegans, which allows researchers to study gene expression and regulation with greater precision and accuracy.
  • Disease Modeling: Using CRISPR/Cas9 knockin technology, disease-associated mutations or specific genetic modifications can be introduced into C. elegans. the precise localization of target trajectories allows the creation of C. elegans models that accurately mimic human disease states.
  • Drug Screening: In drug screening, C. elegans models are a simple and attractive model system. C. elegans models constructed by CRISPR/Cas9 knockin technology can be used for high-throughput screening experiments for drug discovery and genomics research.
