Abstract
The present invention relates to a device and method for separation of proteins and other biomolecules. A preferred use is for sample preparation of crude as well as pre-fractionated samples. In a preferred embodiment, the device of the present invention is a pipette tip having dual channels, one for inlet of sample and one for outlet. The outlet, but not the inlet, channel is provided with sample separation media for separation of a desired biomolecule from a sample. The flow through the sample separation media is unidirectional.
Claims9
