Agarose
Agarose — A polysaccharide polymer used as a gel matrix in electrophoresis and chromatography, commonly employed for size-based separation of large biomolecules.
What Is Agarose?
Agarose is a polysaccharide derived from seaweed used to create gel matrices for electrophoresis and chromatography. In peptide research, agarose-based resins are the standard support for size-exclusion, ion-exchange, and affinity chromatography (Sepharose, Superdex, Ni-NTA agarose).
Applications
- SEC columns: Sephadex/Superdex agarose beads for peptide MW estimation and aggregate analysis
- IMAC: Ni-NTA agarose for His-tag recombinant peptide purification
- Protein A/G: Agarose beads for antibody purification and immunoprecipitation
