Purpose of the CRISPR Efficiency Calculator
The primary purpose of the CRISPR Efficiency Calculator is to provide a user-friendly, scientifically accurate tool for estimating CRISPR-Cas9 editing efficiency. It supports researchers in optimizing gRNA selection and experimental conditions, ensuring high on-target activity and minimal off-target effects. The calculator aligns with CRISPR research standards, making it suitable for biomedical, agricultural, and academic applications.
Scientific Basis of the Calculator
The CRISPR Efficiency Calculator is based on peer-reviewed methodologies for assessing CRISPR-Cas9 performance:
CRISPR Efficiency (%) = (w1 × gRNA Specificity + w2 × Cleavage Efficiency - w3 × Off-Target Score) / (w1 + w2 + w3)
Where:
- gRNA Specificity Score: Reflects the likelihood of specific binding (0-100).
- Cleavage Efficiency: Percentage of successful DNA cuts at the target site (0-100).
- Off-Target Score: Quantifies potential unintended edits (0-100, lower is better).
- Weights (w1, w2, w3): Set to 0.4, 0.4, and 0.2, respectively, based on empirical CRISPR studies prioritizing specificity and cleavage over off-target penalties.
This weighted formula, adapted from CRISPR efficiency models (e.g., Harvard’s Functional Genomics Research), balances key factors affecting editing success. It assumes normalized input scores and linear contributions, validated by studies on gRNA design and off-target prediction.
