- Put cut out gel in 0.5mL tube (with hole at bottom and centrifuged the tube at 15,000 rpm, for 3 min at RT.
- Transfered the gel remaining in 0.5 mL tube to 2.0 mL tube below with pipette tip.
- Added 900 ul of 1X TE buffer
- Vortexed for 3.5hr at 37 C in incubator
- Centrifuged at 15,000 rpm for 3 min at RT
- Transfered the clear spnt. to Nanosep column and centrifuged at 15,000 rpm for 3 min
- Transfered the lower layer to Nanosep again and centrifuged at 15,000 rpm for 3 min
- Transfered spnt to fresh 1.5 mL tube (volume ~ 400ul/ tube)
- Precipitated with 1000ul of 100% EtOH, 1.4ul of Glycoblue, 40ul of 3M NaoAc pH 5.2
- Vortexed and placed the 6 tubes at -80C overnight
