a method that separates DNA fragments by their sizes. The bands of the gel are detected, and then the sequence is read from the bottom of the gel to the top, including bands in all four lanes.

Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code.

Next-generation DNA sequencing has started a revolution ... this is very similar to the way in which gel or capillary sequencing is done,” notes Block. The results of initial experiments were ...

and Nanopore DNA sequencing. Sanger sequencing (left) sequences 500-700 bases per reaction with 16 reactions per gel. Massively parallel DNA sequencing (center) sequences 100-5,000 bases per reaction ...
