Abstract
The present invention provides a method for isolating nucleic acid from a sample, preferably from a biological sample. This method involves applying the biological sample to a hydrophobic organic polymeric solid phase to selectively trap target nucleic acid and removing nucleic acid with a nonionic surfactant. Another method involves treating a hydrophobic organic polymeric material with a nonionic surfactant, washing the surface, and subsequently contacting the treated solid organic polymeric material with a biological sample to reduce the amount of nucleic acid that binds to the organic polymeric solid phase.
