There is no definite or standard time frame because the degradation rate will be related to properties of the microbial community of the sample. The ability to detect eDNA from target species does demonstrably decline over time from stored filter samples. Extracted eDNA is retained in a buffered solution and it is more stable than eDNA on the filter.
How long do preserved samples last?
