Nextera modification, Adding T7
- 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
- adapters will be redesigned for both adapter 1 and adapter 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
- Current sequences and method used by nextera protocol:

- modification and addition of T7 with in place of adapter sequences
- ME sequence + Blue or orange sequence = length of nextera read primer 1, nextera read primer 2.
- Adapter 1 to Blue primer, Adapter 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.
