MDA Bisulfite Converted Sequencing Library Consturction

Objective

  • Work on sperm/ESCs control cell samples plus GM12878 gDNA
  • Sample List
  1. A1-100 sperm cells
  2. A2-100 sperm cells (repeat)
  3. B1-100 ESCs
  4. B2-100 ESCs (repeat)
  5. C-600pg GM12878 gDNA
  6. D-1.2ng GM12878 gDNA
  7. E-NTC

Overview

  • Proteinase K Digestion
  • Bisulfite conversion
  • MDA
  • EtOH precipitation
  • Nextera Library Construction (Low input protocol)
  • Page Analysis
  • Sanger Sequencing

Protocol

Proteinase K Digestion

  • Label tubes A1, A2, B1, B2
  1. Sperms: ~50cell/tube; 15 tubes
  2. ES cells: ~50cell/tube; 15 tubes
  • Thaw 4 tubes on ice, we will use 100cells per reaction

Bisulfite Conversion

  • Setup two more 600pg GM12878 gDNA reactions for Noi to perform capture using the 330k probe set
  • Proceed with Zymo column based method with improvement tweak protocol
  • Elute with 11ul EB Buffer

Heat Denature

  • 92C for 30 sec
  • Transfer to ice immediately

MDA

30C 60 min, 85C 3 min, 4C hold

Ethanol Precipitation

Nextera Library Construction (Low input protocol)
