Online Inquiry

Gene knockout services offer a powerful approach in molecular biology for understanding gene function and creating disease models. This advanced technique involves the complete inactivation or "knocking out" of a specific gene, allowing researchers to study the resulting phenotypic changes and gain insights into the gene's role in biological processes. Gene knockout is an essential tool for genetic research, enabling the dissection of gene pathways and the development of therapeutic strategies.

Overview Service Process Examples and Solutions Applications Frequently Asked Questions


Gene knockout involves the targeted disruption of a specific gene's function. This is typically achieved using advanced gene-editing technologies such as CRISPR/Cas9, TALENs (Transcription Activator-Like Effector Nucleases), or zinc finger nucleases. These tools create double-strand breaks at specific locations within the genome. The cell's repair mechanisms then introduce insertions or deletions (indels) during the repair process, leading to the loss of function of the targeted gene. The precision and efficiency of these technologies make gene knockout a valuable method for studying gene function and developing disease models.

Service Process

The process of gene knockout involves several critical and interrelated steps:

  1. Target Identification: Selecting the specific gene to be knocked out based on the research objective or therapeutic goal. Accurate target identification is crucial for the success of the knockout process.
  2. Guide RNA Design: For CRISPR/Cas9, designing guide RNAs that direct the nuclease to the precise DNA sequence to be disrupted. This step ensures specificity and accuracy in creating double-strand breaks.
  3. Delivery of Editing Components: Introducing the gene-editing tool and guide RNA into the target cells using methods such as electroporation, viral vectors, or lipid nanoparticles. Efficient delivery is vital for the successful uptake and activity of the editing components.
  4. Selection of Knockout Cells: Isolating cells that have successfully undergone gene knockout. This selection process may involve the use of selectable markers or advanced sorting techniques to enrich the population of knockout cells.
  5. Validation: Confirming the successful knockout of the target gene through sequencing and functional assays. This step ensures that the gene has been effectively inactivated and that the resulting cells exhibit the expected phenotypic changes.
