A method to rapidly generate single stranded DNA for dideoxy sequencing following the polymerase chain reaction is described. By incorporating biotin in one of the amplification primers, we are able to physically separate the two DNA strands produced in the polymerase chain reaction. After amplification, the mixture is passed through a column containing streptavidin agarose. The strand produced by the biotinylated primer is bound in this matrix. The unbiotinylated strand is eluted with 0.2 N NaOH and sequenced by the dideoxy method. This method was utilized to sequence mitochondrial DNA from crude genomic DNA and to determine the sequences of four clones containing human mitochondrial DNA as a test of its accuracy. The use of biotin-facilitated separation permitted us to amplify and sequence DNA samples in a single day.
