Overview Service Process Examples and Solutions Applications Frequently Asked Questions


CRISPR/Cas9 knock-in involves the targeted insertion of specific DNA sequences into the genome. This is typically achieved by creating double-strand breaks at the desired genomic location using CRISPR/Cas9 technology, followed by the introduction of a donor template containing the desired sequence. The cell's homology-directed repair (HDR) mechanism integrates the new genetic material into the genome. This technique enables precise genetic modifications, making it a powerful tool for functional genomics, disease modeling, and therapeutic development.

Service Process

The process of CRISPR/Cas9 knock-in cell line construction involves several critical and interrelated steps:

  1. Target Identification: Selecting the specific genomic locus for the knock-in based on the research objective or therapeutic goal. Accurate target identification is crucial for the success of the knock-in process.
  2. Donor Template Design: Designing a donor template that carries the desired DNA sequence flanked by regions homologous to the target site. This template guides the integration of the new sequence during the repair process.
  3. Guide RNA Design: For CRISPR/Cas9, designing guide RNAs that direct the nuclease to the precise genomic location. This step ensures specificity and accuracy in creating the double-strand break.
  4. Delivery of Editing Components: Introducing the gene-editing tool, guide RNA, and donor template into the target cells using methods such as electroporation, viral vectors, or lipid nanoparticles. Efficient delivery is vital for successful HDR.
  5. Selection and Expansion: Isolating and expanding the successfully edited cells. This selection process may involve the use of selectable markers or advanced sorting techniques to enrich the population of knock-in cells.
  6. Validation: Confirming the successful integration of the new sequence through sequencing and functional assays. This step ensures that the knock-in is precise and that the cells exhibit the expected phenotypic changes.
