Nanomicro Tech offers a series of hydrophobic
interaction chromatography (HIC) media for high efficiency separation and
purification of proteins and peptides. HIC is used to separate proteins on the
basis of relative hydrophobicity.Therefore gentle binding and
elution condition of HIC allows a better retaining of the biologic activity of
the target protein than RPC in which organic solvents are applied.
The strength of the hydrophobic interaction
is influenced strongly by the nature of the salt components in the mobile
phase. The salt concentration needed depends on the protein hydrophobicity and
solubility. HIC is particularly attractive for protein purification after ion
exchange and affinity chromatography, where the sample with high salt
concentration can often be applied directly to HIC. By combining HIC with ion
exchange or affinity chromatography, the purification of biomolecules can be
completed efficiently.
