Proteins & Peptides Simplified

BioSep™ Gel Filtration (GFC/SEC) columns are used to analyze and/or characterize proteins, peptides, and other biomolecules, including antibodies, immunoglobulins, protein complexes, protein aggregates, and desalting. BioSep columns offer many important benefits to keep your research, method development/validation, and ongoing size exclusion separations SIMPLE.

• High Efficiencies for Greater Resolution
• Expanded Resolution Windows
• Excellent Reproducibility
• Highly Inert for Better Recovery and Quantitation
