Semiconductor sequencing: how many flows do you need?

摘要

Motivation: Semiconductor sequencing directly translates chemically encoded information (A, C, G or T) into voltage signals that are detected by a semiconductor device. Changes of pH value and thereby of the electric potential in the reaction well are detected during strand synthesis from nucleotides provided in cyclic repeated flows for each type of nucleotide. To minimize time requirement and costs, it is necessary to know the number of flows that are required for complete coverage of the templates.
