The present invention provides an aqueous composition and method for extracting nucleic acid from a sample of bodily fluid, such as saliva, such that the nucleic acid within said sample remains stable for at least fourteen days at room temperature. The composition permits direct use of the extracted and stored DNA in an amplification reaction without further processing.

Compositions and method for storage of nucleic acid from bodily fluids

An aqueous composition comprising a denaturing agent, a chelator, a buffering agent and a protease for the extraction of nucleic acid from a sample of bodily fluid, such as saliva, such that the extracted nucleic acid is stable for at least fourteen days at room temperature and can be directly utilized in an amplification reaction without further processing. In particular, said composition comprises SDS, Cyclohexanediamine tetraacetate, Tris-HCl and proteinase K. A method and kit for the amplification of DNA directly from a bodily fluid, comprising said composition, is further provided.
