DNA extracts generated with KAPA Express Extract may be stored at -20 °C for use in multiple PCRs over a period of time. Storing in smaller aliquots is also suggested. A 1:10 dilution of the DNA extract in TE Buffer is recommended for long-term storage, to ensure that the DNA is stored in a buffered environment. However, the dilution factor may be varied between 1:1 and 1:20, depending on the downstream application and yield of DNA. For downstream applications that are sensitive to EDTA, TE may be replaced with 10 mM Tris-HCl, pH 8.0-8.5.
