Abstract
The present invention relates to a device method and kit for the convenient and rapid isolation and purification of nucleic acids, proteins, peptides, carbohydrates and oligosaccharides from heterogeneous biological samples. The device comprises a membrane assembly comprised of layers of microporous, polymeric membranes functionalized with ion-exchange groups. The device is reusable for like samples, relatively inexpensive compared to currently available separation techniques and is disposable, thereby avoiding cross-contamination of biological samples.
