I. AGE of PCR Samples

  • Make Gel:
  • Measure out 0.50131 g of agarose and add to a 250 mL E-flask
  • Add 50 mL of 0.5x TBE buffer and swirl to mix
  • Cover flask with a Kimwipe and microwave for ~1 minute until clear
  • Allow to cool to ~60 oC and pour into beaker for ethidium bromide (EtBr)
  • Add 1 uL of EtBr stock to agarose and swirl to mix
  • Immediately pour gel into tray with combs
  • Allow to solidify, then remove the comb and tape and place the tray in the gel box with the wells closer to the black electrode
  • Make sure it is submerged in TBE buffer
  • Load Gel:
  • Mix samples as drops on a piece of parafilm
  • Mix:
Ladder (Invtrogen 1 kb plus) Sample
*5 uL DNA ladder
*1 uL 6x Loading Dye 		*6.3 uL dH2O
*1.7 uL 6x Loading Dye
*2.0 uL DNA
  • Load ~10 uL on gel according to the following chart (except ladder which is 6 uL):
Lane 1 2 3 4 5 6 7 8
NEB 2-log ladder - P1 P2 HF1 HF2 LR1 LR2
  • Store DNA at 4 oC
  • P = Phusion, HF = KAPA HiFi, LR = KAPA LongRange
  • Run Gel:
  • Close gel box and turn on power pack
  • Run gel at 30 V for 20 min to stack gel
  • Run gel at 75 V until the markers have reached ~3/4 of gel
  • Image Gel:
  • RESULTS:
