Abstract
An apparatus and method for separating a biomolecule from one or more contaminants in a sample. The apparatus can include a unitary device comprising a plurality of fractionation devices, each reservoir comprising a filter, each reservoir adapted to contain a solid phase, the solid phase adapted to separate the biomolecule and the contaminant by fractionation. The filter can have an average pore size that allows the sample to pass therethrough while substantially preventing the solid phase from passing therethrough. The method can include moving the sample past the solid phase in each reservoir to separate the biomolecule from the contaminant by fractionation to obtain an isolated biomolecule.
Claims13
A method for isolating a biomolecule from a sample, the sample comprising the biomolecule and a contaminant, the method comprising:
- providing a unitary device including a plurality of fractionation devices, each fractionation device including a reservoir, the reservoir comprising a filter, the reservoir adapted to contain a solid phase, the solid phase adapted to separate the biomolecule from the contaminant, the filter adapted to inhibit passage of the solid phase therethrough while allowing passage of the sample therethrough;
- and
- moving the sample past the solid phase in the reservoir to separate the biomolecule from the contaminant by fractionation to obtain an isolated biomolecule.
