EtOH Precipitation[edit]
- Put cut out gel in 0.5mL tube (with holes 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 60 min at 37 C in incubator
- Centrifuged at 15,000 rpm for 3 min at RT
- Transfered the clear spnt. to 8 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 (~450ul per tube)
- Precipitated with 1000ul of 100% EtOH, 1.4ul of Glycoblue, 45ul of 3M NaoAc pH 5.2
- Vortexed and placed the 8 tubes at -80C
- Spun 8 tubes at 10,000rpm at 4C for 30min
- Discard supernatant and add 650ul 75% EtOH and spin at 14,000rpm at 4C for 5min
- Discard supernatant and let dry in hood for 10min
- Resuspend each tube with 10ul (80ul total)
TBU Gel Quantification[edit]
- Diluted Agi26k0gap 10X
- 2ul Agi26k0gap + 8ul H2O + 10ul 2X TBE-Urea buffer
- Made DNA Low Mass Ladder with 0.5, 1, and 2 ul

- Agi26k0gap Concentration: 56.9 ng/ul
- Total Mass: 56.9 ng/ul * 80ul = 4.55 ug
- Total Amount: 4.55ug /(193nt*325 Da/nt) = 72.6 pmole (908nM)
