USE OF LAYERED DOUBLE HYDROXIDES FOR THE ENRICHMENT OR DEPLETION OF BIOMOLECULES FROM LIQUID OR FLUID MEDIA

摘要

Use of a double hydroxide layer (I) from natural or synthetic hydrotalcite or compounds with hydrotalcite structure, to store a compound of biomolecules, preferably peptides, depsipeptides, peptide nucleic acid and proteins, is claimed, where: (I) is in non-calcinated form; the molar ratio of M 2> +>to M1 3> +>is 2.5:1 and the weight ratio of M 2> +>to M1 3> +>, preferably MO to M1 2O 3is maximum of 2.2:1. Independent claims are included for: (1) a composition comprising (I) and the biomolecule; and (2) a process comprising: (i) contacting the liquid or fluid medium comprising the biomolecule with (I), as a sorbent; (ii) adding the agglomerated- or stored- biomolecule into (I); and (iii) removing the agglomerated- or stored- biomolecule with (I).
