Roche/454 pyrosequencing , useful for high throughput sequencing techniques. This method utilizes pyrosequncing which allows for sequencing as the sequence read out can be achieved at the same time as the sequence is extended.

High- throughput screening is the use of automated equipment to rapidly test thousand to millions of samples for the biological activities at the model organism, cellular, pathway or molecular level.Many DNA samples can be sequenced simultaneously.
