Hydrophobic Interaction Chromatography
Hydrophobic Interaction Chromatography (HIC) is a powerful chromatography technique used to separate and purify proteins, peptides, and other biological molecules based on their hydrophobicity or hydrophobic properties. In HIC, the analytes are first bound to the stationary phase and subsequently eluted by an increasing organic, or hydrophobic, content of the eluent. This technique is particularly useful for separating molecules that have similar charge characteristics, enabling the resolution of complex protein mixtures. HIC is a highly efficient method for separating proteins from un-purified samples and allows for the study of the structural and functional properties of large biomolecules, such as enzymes and antibodies. Moreover, this technique is particularly useful for the purification of therapeutic proteins, and is widely used in bioprocessing and proteomics applications.
