Biocompatible polymeric monoliths for protein and peptide separations

Area of Science:

• Chromatography
• Biomaterials Science
• Biochemistry

Background:

• Biocompatibility is crucial for chromatographic stationary phases to prevent nonspecific adsorption of biomolecules.
• Preserving the structure and biochemical functions of proteins and peptides is essential during separation.
• Polymeric monoliths offer advantages in chromatographic separations due to their porous structure.

Purpose of the Study:

• To introduce the concept of biocompatibility in chromatographic stationary phases for biomolecule separation.
• To review biocompatible polymeric monoliths, focusing on polyacrylamide- and poly(meth)acrylate-based materials.
• To discuss synthetic approaches for creating biocompatible monoliths and their applications in enzyme reactors.

Main Methods:

• Review of literature on biocompatible polymeric monoliths for protein and peptide separations.
• Analysis of size exclusion, ion exchange, and hydrophobic interaction chromatographic modes.
• Summary of synthetic strategies including surface modification and direct copolymerization.

Main Results:

• Polyacrylamide- and poly(meth)acrylate-based monoliths demonstrate biocompatibility for biomolecule separation.
• Integration of polyethylene glycol into poly(meth)acrylate monoliths effectively reduces nonspecific protein interactions.
• Biocompatible monoliths are applicable in enzyme reactors, maintaining enzymatic activity.

Conclusions:

• Biocompatible stationary phases are vital for accurate biomolecule analysis.
• Polymeric monoliths, particularly those incorporating hydrophilic polymers like polyethylene glycol, offer promising solutions for reducing nonspecific adsorption.
• Advancements in synthesis enable the direct creation of biocompatible monoliths for improved chromatographic performance and enzyme applications.
