DNA Extractions – Ab Endo 2011 Water Filters

Extracted DNA from 2011 water filters for the Ab Endo project (see spreadsheet: Ab Endo Samples).

DNA was extracted from filters using the Qiagen DNeasy Blood & Tissue Kit (spin column protocol). Filters were incubated in 400uL of Buffer AL (twice the volume in the Qiagen protocol in order to completely coat the filters) and 50uL of Proteinase K (twice the volume in the Qiagen protocol) at 56C O/N. After incubation, 400uL (twice the volume in the Qiagen protocol) of 100% EtOH was added to each tube and vortexed thoroughly. The supernatant was transferred to the Qiagen spin columns and the Qiagen protocol was followed. Samples were eluted with 100uL of Buffer AE.
