PAGE-Size Selection of 20 gap probes

  • Noi said that the band on the previous TBU gel looked relatively faint and recommended putting 3ug of DNA per well instead of the usual 2ug to increase yield
  • I will run 3 gels each with 60ul (~3.4 ug of DNA each)

Sample

Components 1X Volume 3X Volume
Enzyme digested probes (~10ug/180ul) 55 165
TBE-Urea Buffer 2X 55 165
Water 0 0
Total 110 330

3 Low Mass DNA Ladders

Components 3X Volume
Low Mass DNA ladder (1 ug/ul) 3
TBE-Urea Buffer 2X 15
H2O 12
Total 30
  • Ran the 3 gels at 220V for 30min
  • Cut out band below 200bp
