Glossary Term
Proteinase K Digestion
Extraction MethodologyEN
Definition
An enzymatic pre-treatment in nucleic-acid extraction that degrades proteins and nucleases, releasing nucleic acids from clinical material before binding, wash, and elution steps.
Extended Notes
Digestion conditions (temperature, duration, surfactants) determine lysis efficiency across specimen types and matter most for organisms with robust walls or intracellular locations. Extraction comparability studies should specify the digestion step, because it changes downstream performance.
