Abstract

Provided is a magnetic separation device comprising a container having one or more outer surfaces; at least one flexible magnetic sheet; and a non-permanent adhesive that is used to detachably secure an outer surface of the container to a flexible magnetic sheet. A method of using the magnetic separation device according to the present invention comprises obtaining a fluid containing a mixed population of biological molecules, from which it is desired to separate at least one subpopulation of biological molecules; mixing the fluid with a magnetic separation reagent; contacting the mixture with the fluid holding chamber of the magnetic separation device; incubating the mixture for a sufficient time to allow for complexes to form between the subpopulation of biological molecules and the magnetic separation reagent; positioning the magnetic separation device in a position that magnetically attracts the complexes towards the flexible magnetic sheet, and thereby holds them in position in the container; and removing the remainder of the fluid from the magnetic separation device.
