WGBS sequencing library preparation using KAPA protocol (Eppendorf) and epMotion (Repeat!)

Amplification of bisulfite sequencing llibraries with N2 barcoded primers

  • Test if the adapter ligation reaction worked before amplify the libraries with barcoded primers
  • Loaded 2.5 ul of bis-cvt DNA and 2.5ul of amplified amplicons

  • Purified sequencing libraries with 0.8x vol AMPure bead with epMotion (3 strips), eluted with 25ul EB for each well -> total volume at the end ~70ul

PAGE quantification of 400-600bp fragments

  • Dr. Zhang suggested to cut the band around 400-600bp because 250bp is too short for PE sequencing.
  • Perform PAGE size-selection of the size range 400-600bp for a small scale sequencing. Then pooled 60ng of each library and performed PAGE size-selection.

PAGE size-selection

File:ZhangLab 2 2012-08-02 18hr 23min-PAGE-SS.jpg

  • Note: From the image, it seemed like I cut the gel a little smaller than 600bp
  • Resuspend with 12ul H2O each tube -> total volume 24ul.
  • Quantify concentration by PAGE quantification (also verify the size of sequencing libraries) and by dsDNA Qubit
  • Library ID: NP_WGBS_HAPMAP1-8_July27
