Isolation of nucleic acid
First Claim
1. A method of isolating genomic DNA from a sample, said method comprising (a) contacting said sample with a detergent and a solid support in the absence of any chaotropic agent, the solid support comprising an organic polymer, whereby soluble genomic DNA in said sample is bound to the support in a sequence-independent manner in the presence of the detergent and absence of any chaotropic agent, and (b) separating said support with bound genomic DNA from the sample.

Abstract
The present invention provides a method of isolating nucleic acid from a sample, said method comprising contacting said sample with a detergent and a solid support, whereby soluble nucleic acid in said sample is bound to the support, and separating said support with bound nucleic acid from the sample. Where the method of the invention is used to isolate DNA, it may conveniently be couple with a further step to isolate RNA from the same sample.
