    Nanopore Ultra-long Sequencing (PromethION platform)


    Introduction


    Nanopore platforms enable single-molecule sequencing by directly detecting changes in electrical current as DNA strands pass through nanopores. This technology supports read lengths of hundreds of kilobases (kb). When combined with Sailgene’s proprietary ultra-long DNA extraction kit, read lengths with an N50 exceeding 150 kb can be achieved.

    Sample Requirements


    1.Plant samples are recommended to send newly grown young leaves.

     

    2.Animal samples are recommended to give preference to fresh blood, followed by liver and other tissues.

     

    3.Unconventional samples do not guarantee sequencing yield.

     

    Nanopore sequencing unconventional samples are as follows:

     

    1) plants with a lot of secondary metabolites;

     

    2) oceans and aquatic products (animals and plants, algae, etc.);

     

    3) amphibians, birds, etc.
