Oxford Nanopore Technologies (ONT) indeed allows for sequencing long reads, potentially up to several hundred kilobases. This depends highly on sample quality and DNA fragment lengths. However, to have a very competitively priced product we us a library preparation method which includes the adapters with minimal fragmentation (see examples in the troubleshooting guide). The resulting reads will not have the full-length amplicon size, but rather with a long-tailed size distribution.
For a full-length amplicon library preparation with adapter ligation the “premium” amplicon sequencing service>> can be used.
