SgRNA (short guide RNA) design is the process of designing RNA molecules for the CRISPR-Cas9 genome editing tool. The CRISPR-Cas9 system is composed of Cas9 protein and guiding RNA (sgRNA), which can accurately cleave specific DNA sequences, thereby achieving genome editing and repair.
The design of sgRNA involves selecting appropriate DNA target sequences and designing appropriate RNA sequences to form stable Cas9 sgRNA complexes after binding to Cas9 protein. This complex can recognize and bind to the corresponding sequence located on the target DNA, and trigger double stranded DNA breaks at specific locations. The broken DNA can be repaired through natural cellular repair mechanisms, thereby achieving genome editing. When designing sgRNA, multiple factors need to be considered, such as the specificity, accessibility, structural stability of the target sequence, and avoidance of interaction with non target sequences.
The quality of sgRNA design is crucial for the effectiveness and accuracy of the CRISPR-Cas9 system. Appropriate design can maximize the success rate and specificity of genome editing, while reducing the impact and uncertainty on non target sequences. Therefore, sgRNA design is a crucial step in the research and application of the CRISPR-Cas9 system.

Service Process
Our sgRNA Design Service follows a systematic process to ensure the delivery of high-quality sgRNA sequences. Here are the steps involved:
- Project Consultation: We start by understanding your gene editing goals and experimental requirements. This initial consultation helps us gather all the necessary information to design sgRNAs that align with your specific research objectives.
- Target Selection: Based on your input, we assist you in selecting the target gene and defining the desired modifications. Our team takes into account factors such as gene function, accessibility, and potential off-target effects to help you make informed decisions.
- sgRNA Design: Using state-of-the-art algorithms and bioinformatics tools, our experts design highly efficient sgRNA sequences for your specific targets. We consider factors such as efficiency, specificity, and potential secondary structures to ensure the optimal design of the sgRNAs.
- Off-Target Analysis: To minimize the chances of unintended effects, we perform comprehensive off-target analysis. By comparing the designed sgRNA sequences against the reference genome, we identify potential off-target sites and assess their likelihood of causing unintended genetic modifications.
- Delivery: Once the design is complete, we deliver the optimized sgRNA sequences to you. Along with the sequences, we provide detailed reports that include information about the target gene, designed sgRNAs, off-target analysis results, and any additional insights that may be relevant to your research.
