A method of whole genome amplification of a nucleic acid sample comprising providing a starting template of the nucleic acid sample, bringing the template together with blocking DNA, bringing the template together with DNA polymerase, and multiple displacement amplification of the template. The method can be used with a starting template of less than 1 ng of the nucleic acid sample.
