Oxford Nanopore Field Sequencing Kit

Oxford Nanopore Technologies has launched a Field Sequencing Kit for sequencing library preparation from genomic DNA that requires no refrigeration. The kit requires 400 nanograms of high molecular weight DNA as input, and generates libraries in 10 minutes using a two-step protocol. A transposase simultaneously cleaves template molecules and attaches tags to their ends. After that, rapid sequencing adapters are added to the tagged ends. The unopened kit is shipped cold and is stable for up to one month at 30° C and up to three months at 2° C to 8° C.
