Color-blind method opens new doors in DNA sequencing

...E gives brighter signals and collects more of that signal by eliminating the need for a prism to separate the light into colors." Metzker is also seeking to develop a chip-based imager than could be used in his overall project on sequencing-by-synthesis (SBS), which is funded by the National Human Genome R...
