First Claim
Patent Images
1. A method for amplifying nucleic acid templates of different sequences comprising:
- a) amplifying nucleic acid templates on a solid support in the presence of an additive capable of increasing efficiency of amplification of GC rich nucleic acid templates or decreasing efficiency of amplification of AT rich nucleic acid templates, wherein a subset of nucleotide types are incorporated into copies of the templates at a lower efficiency compared to at least one other type of nucleotide, thereby producing a plurality of different copies; and
b) using the plurality of different copies as templates in a second cycle of amplification.

Abstract
Methods for amplifying nucleic acids are provided. The methods can be used to minimize sequence specific bias caused by the preferential amplification of certain nucleic acid sequences. Methods are described which can lower the efficiency of AT rich templates relative to GC rich templates, thereby minimizing GC bias during amplification reactions with multiple templates of different sequence. The methods are suited to solid phase amplification, for example, utilizing flow cells.
