Hydrophobic Interaction Chromatography Media
Cellufine™ Butyl, Phenyl

For purification of proteins and macromolecules

Hydrophobic Interaction Chromatography (HIC) is a method which separates proteins on the basis of their differential interactions with a mildly hydrophobic surface.


HIC media are porous chromatography particles, manufactured from crosslinked cellulose to which either a butyl, phenyl or octyl functionality has been covalently bonded via a short spacer.


Factors which affect hydrophobic interactions include: salt concentrations, temperature, pH, surfactant and organic solvents. Usually the higher the ionic strength (salt concentration) the stronger the hydrophobic bond. Consequently the interaction is enhanced by conditions inverse to that of ion exchange chromatography. HIC is, therefore, an effective complementary tool for separating and purifying substances which are difficult or cannot be separated by ion exchange.

Hydrophobicity of Matrix


The degree of hydrophobicity increases in the order of Butyl < Phenyl. In general hydrophobic proteins will be more strongly adsorbed to Cellufine Phenyl than Cellufine Butyl. However, if the protein is too strongly adsorbed, difficulty may be experienced in elution. The aromatic nature of the Cellufine Phenyl may, in certain cases, give improved selectivity compared to Cellufine Butyl. Consequently it is difficult to generalize and each application needs to be evaluated separately to select the optimal media functionality.

Flow Properties


The semi-rigid structure of Cellufine HIC, combined with the spherical bead shape, gives excellent flow rates with higher operating pressures. Flow rates in excess of 100 cm/hr are achieved at pressure drops of 1 bar, even in large diameter process columns.
