Sequencing single-stranded libraries on the Illumina NextSeq 500 platform

الأصل · EN

Single-stranded libraries generated from ancient DNA extracts have specific sequencing requirements. The short library molecules typically associated with ancient DNA templates are expected to behave differently during the annealing to the flow cell and subsequent cluster generation (bridge PCR), requiring optimisation of loading amounts to obtain optimal and consistent cluster densities. For the past 3 years, we have carried out sequencing of single-stranded libraries on the Illumina NextSeq 500 sequencing platform at the Institute for Biochemistry and Biology, University of Potsdam. We report our optimisations here. This document may be useful for other researchers wishing to sequence single-stranded libraries on the NextSeq 500 platform. It does not replace the excellent documentation provided by Illumina (links provided below), but rather serves as additional information specific to single-stranded libraries. The original papers describing the library protocol should also be studied in detail, and complement the information presented here.
