Immobilization of a supercoiled DNA, useful in analysis of DNA repair, comprises depositing the DNA sample on a porous polymeric film, and immobilizing the DNA by passive diffusion into the film

摘要

Immobilizing a supercoiled DNA comprises depositing a sample of supercoiled DNA on the surface of a porous polymer film, and immobilizing the DNA by passive diffusion in the film. The polymer film is preferably formed on a substrate such as a sheet of glass. An independent claim is included for glass sheet support covered in a porous polymeric film containing an immobilized supercoiled DNA.
