The present invention relates to a method of purifying peptides and/or polypeptides, said method comprising or consisting of: (a) loading a sample comprising peptides and/or polypeptides under acidic or neutral aqueous conditions on mixed-phase solid phase extraction (SPE) material, wherein said material consists of or comprises reversed phase/ion exchange material; (b) washing said mixed-phase SPE material with (ba) an acidic or neutral composition comprising at least 50% (v/v) organic solvent; and/or (bb) an acidic or neutral aqueous solution; and (c) eluting said peptides and/or polypeptides from said mixed-phase SPE material with an alkaline composition comprising at least 50% (v/v) organic solvent.

Peptide purification using mixed-phase solid phase extraction material

Disclosed is a sample preparation container for purification and/or enrichment of bio-organic compounds from cellular material, viruses and/or sub-components of these. The container includes a reaction chamber and a chromatography medium. The reaction chamber is for holding the cellular material, etc. and is configured to perform reactions inside. The chromatography medium is configured to purify the bio-organic compounds. The chromatography medium is located at a wall of the reaction chamber, and the wall is closed or sealed and configured to be opened for obtaining purified bio-organic compounds. The sample preparation container further includes a receiving chamber for receiving the bio-organic compounds, that is adjacent to the chromatography medium such that the chromatography medium separates the reaction chamber from the receiving chamber. The outer face of the receiving chamber is closed and configured to be opened for obtaining purified bio-organic compounds.
