Four months later the size of the damaged tissue swath had decreased by nearly 36 percent, and the patients’ heart function had increased by 10 percent.

Amplification followed by base-extension sequencing with py- 43 runs per base — of the target genome, 454 achieved accurophosphate detection in an array of wells. Both groups read racy of one error per 2,500 base pairs. The Harvard group had about the same amount of sequence, 30 million base pairs, in less than one error per three million base pairs with 7× covereach sequencing run. Our system read about 400 base pairs a age. To handle templates, both teams employed capture beads, second, whereas 454 read 1,700 a second.
