Update of THS-seq protocol sequences to use Nextera XT V2 sequences



  • Called illumina and they said it is either sequencer not being cleaned right, or concentrations are off, or sequences in library generation protocol are not compatible. Considering currently old nextera sequences are being used from 5 years ago, and all current systems illumina sequencing systems do not use them, then maybe that is the problem.
