Abstract
The invention relates to a method of preparing template constructs for solid-phase nucleic acid amplification and to use of the templates in methods of solid-phase nucleic acid amplification. The method involves carrying out two ligation reactions: (a) a ligation reaction in which the first end of one or more target polynucleotide molecules are ligated to surface-bound adaptor polynucleotide molecules, and (b) a ligation reaction in which solution-phase adaptor polynucleotide molecules are ligated to the second end of said target polynucleotide molecules, in order to produce one or more template constructs attached to a solid support
