Abstract

A device for automated or manual group separations of complex biological mixtures and methods of use are described. The device is a gel filtration pipette tip having a size exclusion media therein and held in place by a filter at the distal end of the pipette tip and an optional removable or pierceable barrier at the proximal end of the pipette tip. The size exclusion media is wetted by aspirating a solvent from the bottom of the pipette tip and equilibrating the solvent with the size exclusion media. The solvent is then allowed to gravity drain from the pipette tip, allowing the size exclusion media to settle and reproducibly pack into a homogenous gel. Gel filtration separations can then be performed with the gelled size exclusion media.
