Nucleic acid amplification
First Claim
1. A method for nucleic acid amplification, comprising:
- A. forming a reaction mixture within a continuous liquid phase under nucleic acid synthesis conditions by distributing at least two different polynucleotide templates comprising both a first primer binding sequence and a second primer binding sequence, into an array of reaction chambers, wherein the array or reaction chambers is on a support and contains a first universal primer that does not include any target-specific sequence, by introducing a polymerase, a second universal primer in solution, and said at least two different polynucleotide templates into different reaction chambers of the array, wherein the first primer binding sequence is complementary or identical to at least a portion of the first universal primer and the second primer binding sequence is complementary or identical to at least a portion of the second universal primer;
B. forming at least two substantially monoclonal nucleic acid populations by using the polymerase to amplify under isothermal conditions a single one of each of said at least two different polynucleotide templates within said different reaction chambers, by partially denaturing and without first compartmentalizing, within the same reaction mixture of step (a) in the continuous liquid phase, wherein the different reaction chambers are in fluid communication with each other during the amplifying;
C. after the amplifying, distributing a plurality of additional polynucleotide templates into the array of reaction chambers; and
D. amplifying under the isothermal conditions, at least one polynucleotide template of the plurality of additional polynucleotide templates, thereby forming an additional substantially monoclonal nucleic acid population within each of at least one additional reaction chamber of the array of reaction chambers that does not include any other substantially monoclonal nucleic acid population.

Abstract
In some embodiments, the present teachings provide methods for nucleic acid amplification, comprising forming a reaction mixture, and subjecting the reaction mixture to conditions suitable for nucleic acid amplification. In some embodiments, methods for nucleic acid amplification include subjecting the nucleic acid to be amplified to partially denaturing conditions. In some embodiments, methods for nucleic acid amplification include amplifying without fully denaturing the nucleic acid that is amplified. In some embodiments, the methods for nucleic acid amplification employ an enzyme that catalyzes homologous recombination and a polymerase. In some embodiments, methods for nucleic acid amplification can be conducted in a single reaction vessel. In some embodiments, methods for nucleic acid amplification can be conducted in a single continuous liquid phase of a reaction mixture, without need for compartmentalization of the reaction mixture or immobilization of reaction components. In some embodiments, methods for nucleic acid amplification comprise a amplifying at least one polynucleotide onto a surface under isothermal amplification conditions, optionally in the presence of a polymer. The polymer can include a sieving agent and/or a diffusion-reducing agent.
