We have developed a high speed instrument for automated DNA sequence analysis. The apparatus employs laser excitation and a cooled CCD detector for the parallel detection of up to 18 sets of four fluorescently labeled DNA sequencing reactions during their electrophoretic separation in ultrathin (50-100 microns) denaturing polyacrylamide gels. Four hundred and fifty bases of sequence information is obtained from 100 ng of M13 template DNA in less than one hour, corresponding to an overall instrument throughput of over 8000 bases/hr.

UI MeSH Term Description Entries
D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
