Abstract

A method of separating cell nuclei from cells comprises: treating a fluid containing whole cells so as to selectively lyse the cytoplasmic membrane together with a small proportion of the nuclear membranes but leaving a large proportion of the cell nuclei intact; applying the treated fluid to a membrane whereby a mesh of DNA from the lysed nuclei is formed on the surface and captures intact cell nuclei. A device for use in the method is described.
