FAQ-2032
Can DNA yields be increased by prolonging incubation with proteinase K in Buffer ATL?
For most sample types, incubating longer than specified in the pretreatment protocol for the QIAsymphony DNA Investigator Kit does not increase yields. However, lysates can be incubated overnight without negatively affecting the quality of the extracted DNA.
