Patent Images
1. A process for isolating nucleic acids by lysing blood cells, substantially all of which are intact, and removing the nucleic acids emerging from the lysed cells, comprising the steps of:
- a) immobilizing the cells in a porous matrix having ion exchange properties and having voids each having a size sufficient to capture one of the cells;
b) lysing the cells;
c) fixing the emerging nucleic acids on the matrix surface by ion exchange, and subsequently;
d) eluting the nucleic acids.

Abstract
A device and a process for isolating nucleic acids by lysing intact cells and removing nucleic acids emerging from the lysed cells by the following steps:
a) the cells are immobilized in a porous matrix, with the size of matrix voids being in the range of the type of cell to be lysed;
b) the cells are lysed;
c) the nucleic acids are fixated on the matrix surface, and subsequently
d) are eluted.

12. In a process for isolating nucleic acids by lysing blood cells and removing the nucleic acids emerging from the lysed cells, the improvement comprising the steps of:
-
a) before lysing, immobilizing the blood cells in a porous matrix having ion exchange properties and having voids each having a size sufficient to capture one of the cells; b) lysing the captured cells; c) fixing the emerging nucleic acids on the matrix surface by ion exchange, and subsequently; d) eluting the nucleic acids.
