IMPROVEMENTS IN NUCLEIC ACID SEQUENCING

Abstract:

A method of preparing templates for high throughput nucleic acid sequencing, comprising: a) providing a solid support, wherein said solid support comprises a plurality of nucleic acid primers immobilised adaptor nucleic acid sequences which hybridise to one or more of the nucleic acid primers, and the library preparation having a nucleic acid concentration of 400 pM or less; c) allowing single stranded fragments of template nucleic acid to bind to said nucleic acid primers, thereby immobilising said single stranded fragments on said solid support; and d) repeating steps b) and c) at least three further times, i.e. multiple loadings or rounds of template hybridization to improve occupation rates, e.g., of nanowells on a flow cell.
