Samples should be in a high salt concentration to promote hydrophobic interaction. The hydrophobic interaction between the matrix of the column and the dissolved chemical compounds also depends on the hydrophobicity of the gel and the composition of the eluent. It is an efficient mode to remove dimers and high—molecular-weight aggregates in a monoclonal antibody purification process as a polishing step ( 17 ). HIC is a useful separation technique for purifying proteins while maintaining biological activity due to the use of conditions and matrices that operate under less denaturing conditions. Title: Recent Advancement in Application of Hydrophobic Interaction Chromatography for Aggregate Removal in Industrial Purification Process VOLUME: 10 ISSUE: 4 Author(s):Yuefeng Lu, Brian Williamson and Ronald Gillespie Affiliation:Global Process Engineering, Process Development, Amgen Inc., Thousand Oaks, CA 91320, USA. Hydrophobic interaction chromatography (HIC) is a versatile method for the purification and separation of biomolecules by using the function of hydrophobicity. Hydrophilic Interaction Chromatography Normal phase and hydrophilic interaction liquid chromatography (HILIC) are primarily used to separate polar and hydrophilic compounds. Chromatography was first employed in Russia by the Italian-born scientist Mikhail Tsvet in 1900. • Different basis of separation • Weaker interactions → Less structural damage → Maintain high activity 3. The hydrophobic interaction between the matrix of the column and the dissolved chemical compounds also depends on the hydrophobicity of the gel and the composition of the eluent. It was first described by Shepard and Tiselius in 1949 using the term “salting out chromatography.” In this type of chromatography, sample molecules with hydrophobic portion(s) interact with and bind to the hydrophobic groups (e.g., phenyl groups) attached to the column stationary phase. In reversed phase mode very polar compounds are often not sufficiently retained in low percent organic, or even in 100% aqueous mobile phase. Relations between retention times, log P ‐coefficients (octanol/water partition) and K ‐values of isotherms on activated carbon (Freundlich equation) were found. Protein retention mechanism in HIC. Hydrophobic interaction chromatography (1) 1. HIC is a useful separation technique for purifying proteins while maintaining biological activity due to the use of conditions and matrices that operate under less denaturing conditions. Hydrophobic interaction chromatography (HIC) is based on a separation of molecules with respect to their hydrophobicity.It is a commonly used method for intermediate steps and polishing steps in protein purification. Jun 03, 2020 (AmericaNewsHour) -- Global Hydrophobic Interaction Chromatography Market to … In this type of chromatography, hydrophobic groups such as phenyl, octyl, or butyl, are attached to the stationary column.
Relations between retention times, log P ‐coefficients (octanol/water partition) and K ‐values of isotherms on activated carbon (Freundlich equation) were found.

A chromatographic matrix containing hydrophobic groups, binds proteins from aqueous solutions to different extents depending on the protein structures and a range of controllable factors including concentrations of salts, pH, temperature and organic solvents (Fig 2). Understanding water structure on hydrophobic surfaces forward model-based process development for hydrophobic interaction chromatography.
