Abstract

Methods of amplifying genomic DNA are provided which include contacting template genomic DNA, a plurality of random primers, and a DNA polymerase, wherein the ratio of template genomic DNA to random primers is in the range of about 1:10-1:35,000,000 (w/w), inclusive, to produce a reaction mixture; and incubating the reaction mixture under isothermal conditions suitable for DNA synthesis, thereby producing amplified genomic DNA characterized by less than 10 percent gene copy number error. The template genomic DNA used in described methods can be in denatured condition and/or in non-denatured condition to achieve production of amplified genomic DNA characterized by less than 10 percent gene copy number error. In a particular option, the reaction mixture includes detectably labeled nucleotides and detectably labeled amplified genomic DNA characterized by less than 10 percent gene copy number error is produced.
