Day 1
1h 6m 22s
1h 6m 22s
UV sterilize supplies for 2 96 well plates worth of extractions: 1 50mL centrifuge tube, 1 15mL centrifuge tube, 1 box 1,000uL pipette tips, 2 boxes 200uL pipette tips, 24 elution microtube strip caps, steel beads, zirconia beads, and 1 reagent reservoir
Combine 36 mL Buffer ATL (tissue lysis buffer)QiagenCatalog #19076 and 4000 µL Proteinase K (2 ml)QiagenCatalog #19131 in 50mL centrifuge tube, invert gently to mix
Add 200 µL ATL + Proteinase K solution to each sample
Add ~100 µL zirconia beads and 2 steel beads to each sample
Place plates in tissue lyser and run at 30 Hz for 00:02:30 , then rotate plates 180 degrees and lyse at 30 Hz for an additional 00:02:30

22s
Incubate 56 °C for 01:00:00 with weight on top of plate
Note: remove from incubator carefully with weight on top so that caps do not pop off

Place plates in tissue lyser and run at 30 Hz for 00:01:00
1m
Incubate 56 °C overnight with weight on top of plate
Day 2
Day 2
53m 44s
53m 44s
UV sterilize supplies: 4 reagent reservoirs, 24 elution microtube strip caps (clear), 2 boxes 1,000uL tips (plus some extra), 6 boxes 200uL tips (plus some extra), 2 s-blocks, 2 elution microtube plates (dark blue) and 24 strip caps (white), and 6 96 well microplates (for aliquotting final product). Label 6 foil microplate lids for aliquots
Carefully remove plates from incubator, leaving the weight on top, and allow to sit at room temperature for a few minutes before carefully removing weight to ensure strip caps do not pop off
Shake plates by hand for 00:00:15 , rotating plates halfway through
15s
Centrifuge on "short" for 00:00:07

Add 410 µL ALE to each sample
Seal with new caps and shake by hand for 00:00:15 , rotating plates halfway through
15s
Centrifuge on "short" for 00:00:07
7s
Place DNeasy filter plates on top of s-blocks
Transfer lysate to DNeasy filter plate and seal with AirPore tape
Centrifuge 3486 x g, 00:13:00 . Discard flowthrough
13m
Add 500 µL Buffer AW1QiagenCatalog #19081 to each sample, seal with AirPore tape
Safety information
Buffer AW1 contains guanidine salt - do not mix with bleach
Centrifuge 3486 x g, 00:08:00 . Discard flowthrough
