Survival Fraction (Optional)
Plating Efficiency Formula
PE = (Colonies / Cells plated) × 100%
SF = PE(treatment) / PE(control)

Tips for Better PE
- - Use cells in log phase (60-80% confluent)
- - Gentle trypsinization and handling
- - Accurate cell counting
- - Optimal seeding density
- - Fresh, properly conditioned media
