By applying algebraic coding methods to the Sanger dideoxynucleotide procedure, DNA sequences of two templates can be determined simultaneously in only five reactions and data channels. A 5:2 data compression is accomplished by instantaneous source coding of nucleotide sequence pairs into one set of 5-bit block codes. A general algebraic expression, 2n - 1 ≥ 4f, describes conditions under which f DNA templates can be sequenced using n channels. Such compression sequencing is accurate and efficient, as demonstrated by manual 35S autoradiographic detection and automated on-line analysis using fluorescent-labeled primers. Symmetric 5:2 compression is especially useful when comparing two closely related sequences.
