This extraction protocol uses an Extract-N-Amp equivalent solution to quickly and cheaply perform DNA extractions. This protocol has been widely used for dried specimens of macrofungi, but will work for other organismal groups as well. This protocol is an amalgamation of two different protocols that are currently in use by academic labs in the United States.
This protocol is easily scalable for larger batch sizes. The standard protocol assumes 100mL batches. This is enough extraction solution for 5,000 specimens. The primary thing needed to scale up are larger sizes of the sterile vacuum filter flasks. They come in each size you may need - 250mL, 500mL, or 1000mL.
For larger batch considerations:
100mL is enough for ~5,000 extractions
250mL is enough for ~12,500 extractions
500mL is enough for ~25,000 extractions
1000mL is enough for ~50,000 extractions
