Abstract
Use of a composite sorbent having an at least partial coating on a support, which coating comprises essentially polyanilines or derivatives of polyanilines for the separation, isolation, identification, purification and/or detection of biomolecules in particular nucleic acids, proteins, polysaccharides in analytical or preparative scale.
Claims8
A method for separation, isolation, identification, purification and/or detection of nucleic acids in analytical or preparative scale comprising (i) filling, at least partially, a chromatographic column, capillary, or cartridge with a composite sorbent comprising a support at least partially covered by a polymeric coating, the coating comprising polyaniline or derivatives of polyaniline, (ii) applying a sample containing nucleic acids and other substances to the composite sorbent, and (iii) eluting the nucleic acids, separated from the other substances, from the composite sorbent, without utilizing the electrical conductivity of said polyaniline or its derivatives.
A method for separation, isolation, identification, purification and/or detection of nucleic acids comprising (i) applying a sample containing nucleic acids and other substances to a composite sorbent comprising a support at least partially covered by a polymeric coating, the coating comprising polyaniline or derivatives of polyaniline, and (ii) eluting the nucleic acids, separated from the other substances, from the composite sorbent, without utilizing the electrical conductivity of said polyaniline or its derivatives.
A method for separation, isolation, identification, purification and/or detection of nucleic acids comprising (i) applying a sample containing nucleic acids and other substances to a composite sorbent, wherein the composite sorbent is in loose form or packed in a chromatographic column or cartridge, and wherein the composite sorbent comprises a support at least partially covered by a polymeric coating, the coating comprising polyaniline or derivatives of polyaniline, and (ii) eluting the nucleic acids, separated from the other substances, from the composite sorbent, without utilizing the electrical conductivity of said polyaniline or its derivatives, said composite sorbent in loose form or packed in a chromatographic column or cartridge is provided in a kit together with filter materials, reagents, and/or buffers or other devices or chemicals, for performing sample preparations or chromatographic separations.
A method for separation, isolation, identification, purification and/or detection of nucleic acids comprising (i) applying a sample containing nucleic acids and other substances to a composite sorbent, wherein the composite sorbent is in loose form or a membrane-like article, and wherein the composite sorbent comprises a support at least partially covered by a polymeric coating, the coating comprising polyaniline or derivatives of polyaniline, and (ii) eluting the nucleic acids, separated from the other substances, from the composite sorbent, without utilizing the electrical conductivity of said polyaniline or its derivatives, said composite sorbent in loose form or membrane-like article is provided in a kit together with filter materials, reagents, and/or buffers or other devices or chemicals, for performing sample preparations or chromatographic separations.
