What is sgRNA Design?
sgRNA design involves selecting and optimizing guide RNA sequences that direct CRISPR-Cas nucleases to precise genomic locations. Effective sgRNA design requires:
- High on-target activity – ensuring efficient DNA cleavage or modification
- Minimal off-target effects – avoiding unintended genetic alterations
- Compatibility with CRISPR variants – adapting to different Cas enzymes (e.g., Cas9, Cas12a)
The process requires in-depth sequence analysis, genome-wide specificity screening, and algorithm-based prediction models to maximize efficiency and minimize unwanted mutations.
What are the Guidelines for sgRNA Design at BOC Sciences?
