Construction of Solexa sequencing library from padlock captured PCR products using NEBNext DNA Sample Prep Master Mix Set 1 Kit (E6040S/L)

Overview

  • Fragmentation and end-polishing
  • Size Selection
  • Ligation
  • PCR of sequencing Library
  • QPCR quantification

Fragmentation and end-polishing (Make blunt ends with 5'P)

  • The PCR amplicons (200ng-1ug) are fragmented with Covaris sonicator to ~100bp
  • End-Repair Reactions
Fragmented DNA 85ul
10X End Repair Bufer 10ul
End Repair Enzyme Mix 5ul
  • Incubate tubes at RT for 30minutes.
  • Perform a Qiaquick purification and elute with 39ul EB buffer.
