   Quantities: Multiple replicates per enzyme variant and substrate combinationDuration: Standardized incubation periods for enzyme reactionsConditions: Controlled temperature and pH conditions for enzyme assays
   Equipment: protein purification systems, spectrophotometers, reaction chambers

Typical Equipment

• protein purification systems
