Provide an efficient sample preparation device for use in isolating (immunoassay), purifying, and concentrating samples of proteins, peptides, nucleic acids (eg, DNA and RNA), and other biomaterials (eg, cells) This is the object of the present invention. The present invention is a high surface area multi-capillary sample preparation device that is particularly useful for the handling of biological samples, comprising a plurality of uniform capillary tubes coated with a stationary phase and arranged in an integral element. This multi-capillary device is suitable for attachment to pipettes, micropipettes, syringes, or other analytical or sample preparation equipment. |
