Abstract

A solid medium for storage of DNA, including blood DNA, comprising a solid matrix having a compound or composition which protects against degradation of DNA incorporated into or absorbed on the matrix. Methods for storage of DNA using this solid medium, and for recovery of DNA or in situ use of DNA are also disclosed.

Claims

1. A dry solid medium for storage of a sample of genetic material, said dry solid medium comprising:

a fiber matrix for sorbing genetic material thereon; and

a surfactant deposited onto said fiber matrix for protecting the genetic material, applied to said fiber matrix, from degradation.

2. The dry solid medium as set forth in claim 1, wherein said surfactant includes an anionic detergent such as sodium dodecyl sulphate.

3. The dry solid medium as set forth in claim 1, wherein said fiber matrix includes synthetic glass fibers and filaments.

4. The dry solid medium as set forth in claim 1 further including releasing means for releasing the genetic material from said fiber matrix.

5. A method of storing a sample of genetic material by:

sorbing genetic material on a fiber matrix; and

preserving and protecting the genetic material applied to the fiber matrix.
