Nextera modification, Adding T7 after tagmentation[edit]

  • T7 would be added by PCR after tagmentation.
  • IVT will be used for amplification and should result in less sample loss and capture of more insertions
  • adaptors will be redesigned for both adaptor 1 and adaptor 2
  • Efficiency will be high in terms of capture of insertions, but not 100% since PCR is not 100% efficient
  • information taken from "nextera Detailed Nextera Protocol.pdf", and "nextera sample prep protocol 307pl0611.pdf"
  • flowcell sequences present on LC Sciences DMR probes design

modification of Shendure protocol with ME-t7[edit]

  • modification and addition of T7 in place of adaptor sequences
    • see T7 information etc
    • first G in GGG is the +1 site
    • at least 5 nucleotides needed before start of sequence to ensure correct binding
  • ME sequence + Blue or orange sequence = length of nextera read primer 1, nextera read primer 2.
  • Adaptor 1 to Blue primer, Adaptor 2 to Orange primer. Bother will have T7 on them, thus both ends will always be tagged.
    • flipped orientations results in the reversed strandedness of T7 synthesis direction.


Protocol:

  • 1. tagmentation with nextera kit
  • 2. Partially denature at 72C (5-10C higher than the Tm for ME sequences)
  • 3. Anneal a ME-T7 adaptor. make it specific for orange/blue too?
  • 4. Gap filling and ligation. (T4 DNAP/Ampligase as in Shendure protocol)
  • 5. IVT and conversion to sequencing libraries.

Method using PCR for addition of T7 polymerase[edit]

Protocol:

  • 1. tagmentation with nextera kit
  • 2. Addition of T7 adaptors, (adaptor 1, adaptor 2) with PCR amplification
  • 3. In vitro transcription with T7, overnight for 16 hours.
  • 4. RNA fragmentation and then possibly A-tail the RNA
  • 5. cDNA synthesis
  • 6. PolyA addition with Terminal Transferase (if haven't A-tailed the RNA)
  • 7. Addition of bPCR lawn adaptors with primer mix of sequences for (orange, blue, polyT addition)
  • 8. now ready for input into the sequencer with the combined nextera read primer 1, and nextera read primer 2.
