Thermo Scientific's BioBasic columns are designed for separations of proteins, peptides and nucleic acids. Available in a range of reversed-phase, ion-exchange and size exclusion phases, BioBasic columns are suitable for a variety of protein and peptide application needs from sample clean-up to analysis, including proteomics and LC-MS applications.

BioBasic Reversed-Phase columns

BioBasic reversed-phase columns are available in C18, C8 and C4 chemistries. These silica based columns provide superior chromatography because the extra dense bonding chemistry produces a highly stable, reproducible surface. Columns show excellent reproducibility and are ideally suited for LC-MS separations.

  • 300A pore size for improved performance of biomolecules
  • High performance, good efficiency and column lifetimes
  • Ideal for LC-MS applications

BioBasic Ion-Exchange columns

BioBasic AX and SCX silica based columns show excellent performance for proteins, peptides and other ionic species and polar molecules. These ion-exchange materials can be used across a wide range of pH and ionic strength conditions.

In addition to its anion-exchange applications, BioBasic AX can also be used under high organic conditions in the HILIC mode. BioBasic SCX is a versatile strong cation-exchange phase for proteins, peptides and small molecules, also useful for protein fractionations for proteomics analyses by capillary LC-MS, including 2D proteomics combined with reversed-phase.

  • 300A pore size for enhanced protein and peptide separations
  • BioBasic AX for anion-exchange and HILIC
  • BioBasic SCX for cation-exchange

BioBasic SEC columns

BioBasic SEC columns, based on silica with a proprietary polymeric coating, offer the mechanical stability of silica-based size exclusion columns with higher efficiencies than those of polymer-based columns. Four pore sizes are available, making them ideal for molecular weight determination of peptides and proteins and for sample clean-up prior to other analyses.

  • Silica-based media for water soluble compounds
  • Pore sizes from 60 to 1000A
  • Ideal for sample clean-up
