Abstract: The present invention regards a variety of methods and compositions for whole genome amplification and whole transcriptome amplification. In a particular aspect of the present invention, there is a method of amplifying a genome comprising a library generation step followed by a library amplification step. In specific embodiments, the library generating step utilizes specific primer mixtures and a DNA polymerase, wherein the specific primer mixtures are designed to eliminate ability to self-hybridize and/or hybridize to other primers within a mixture but efficiently and frequently prime nucleic acid templates.

Abstract: The present invention regards a variety of methods and compositions for obtaining epigenetic information, such as DNA methylation patterns, through the preparation, amplification and analysis of Methylome libraries. In several aspects of the present invention, there are methods based on methylation-dependent enrichment or depletion of genomic DNA isolated from cellular and cell-free sources. In additional embodiments, there are methods and compositions for single-step high throughput preparations of Methylome libraries.
