Abstract
A fluorescence-based, T7 (Sequenase) dye terminator method for sequencing double-stranded DNA using strings of three contiguous hexamers as primers and single-stranded binding protein is described. In this method, the circular, supercoiled DNA vector pUC19 is first linearized with a restriction enzyme to create a sequenceable template. Sequencing is then accomplished using three cycles of 'denaturation,' annealing, and extension/termination. Twenty-two of 33 hexamer strings tested in a controlled study produced acceptable sequence, with read lengths varying from the mid 300s to the low 400s and a base-calling accuracy of at least 97%. To test its potential utility in directed DNA sequencing, the protocol was then used to completely sequence both strands of pUC19. For this test project, a total of 28 hexamer strings was used with an overall successful priming rate of 75%. The current protocol appears to be sufficiently robust to be used in the finishing phase of a shotgun sequencing project and is amenable to semiautomation. Prospects for using the protocol for full-scale directed sequencing as well as for full automation are discussed.
