Chromatography methods

Depending on the physico-chemical properties of the antibodies, their isotype and their origin (species, matrix, etc.), a variety of purification strategies is applicable:

  • Affinity chromatography: Protein G, Protein A, Nickel sepharose
  • Ion exchange chromatography: anion/cation
  • Hydrophobic interaction chromatography: MEP [Mercapto-Ethyl-Pyridine]
  • Size-exclusion chromatography: gel filtration

Antibody coupling service

Many modifications of antibodies are possible (coupling, fragmentation, etc.) which enables us to obtain effective tools in multiple applications.
We can couple your antibodies to a number of enzymes (HRP, Biotin) and to fluorochromes (FITC)
