Featured are devices, methods and kits for preparation of samples of peptides and proteins from a solution; more particularly to such devices and methods in which carbon nanotubes are utilized for sample preparation and/or purification of peptide and/or protein samples from a solution. A sample to be treated/processed can comprise proteins, peptides or any other molecule having an amine moiety that can be protonated under low pH, such as, but not limited to, pH 5. Such a sample also can contain contaminants such as salts, detergents, etc. that will be eliminated during the sample preparation/purification process of the present invention. The methods, devices and kits of the present invention advantageously provide for the concentration of the sample, removal of contaminants and ease of manipulation of small liquids without the concomitant loss of sample. |
