While Sanger sequencing was highly accurate and less labor-intensive than its predecessors, it still required the use of radioactive reagents and manual sequence recording. In 1986, Leroy Hood’s lab at Caltech replaced the radiolabeled ddNTPs with fluorescently labeled nucleotides, using fluorophores that emitted different colors of light for each base. They were now able to run the products of all four reactions on the same gel and have a computer read the sequence by detecting the color of each fluorescent signal as fragments passed through a laser beam.

Eventually, though, different aphorisms will come into play. Yes, it’s true: You don’t know what you don’t know. But we do know that all good things come to an end. And that what goes up must come down.，推荐阅读一键获取谷歌浏览器下载获取更多信息
