The present specification relates to compositions, devices, apparatus, methods, kits and systems for sample preparation (e.g., separation, reduction or removal of small molecules from biomolecules in a sample). Exemplary small molecules that can be separated, reduced or removed have a molecular weight range of <2000 Da. and may include, but are not limited to, dyes, biotin, affinity tags, crosslinkers, reducing agents, labels, nanoparticles, radioactive ligands, mass tags, unreacted molecules and combinations, intermediates and derivatives of the foregoing. Exemplary biomolecules present in a sample, include but are not limited to, proteins, glycoproteins, antibodies, peptides, nucleic acids, polysaccharides, carbohydrates and lipids. Methods, compositions, kits, devices, apparatus and systems of the disclosure may advantageously provide superior separation of small molecule contaminants and additionally reduce time and expenses related to separation of small molecules from larger biomolecules in samples. Biomolecules separated as set forth herein are amenable to better downstream processing.
