Abstract

Microbial cloning makes Sanger sequencing of complex DNA samples possible but is labor intensive. We present a simple, rapid and robust method that enables laboratories without special equipment to perform single-molecule amplicon sequencing, although in a low-throughput manner, from sub-picogram quantities of DNA. The method can also be used for quick quality control of next-generation sequencing libraries, as was demonstrated for a metagenomic sample.

Highlights

  • Sanger sequencing has long been, and still is, the most used method for DNA sequencing

  • Applying Sanger sequencing on complex sample materials commonly requires an initial microbial sub-cloning step, which is often used for validating next-generation sequencing libraries [2]

  • Generation of polonies According to the Poisson distribution, sample concentration should be kept low to achieve a high proportion of single-molecule polonies among all (Table S1 and Figure S1)
