Causes of Hydrophobic Interactions. So you should review those. A sample of bacteria was concentrated and then resuspended in a solution in which they were lysed. Alternative case 1 consisted of a multimodal resin (hydrophobic and cation exchange) followed by a TFF unit, hydrophobic interaction exchange resin column, and another TFF unit. DOI: 10.1016/S0021-9673(00)94791-5.

Today we performed a Hydrophobic Interaction Chromatography (HIC) to separate the green fluorescent protein (GFP), produced in our bacterial cultures, from other proteins commonly found in bacteria. The image above indicates that when the hydrophobes come together, they will have less contact with water.

American chemist Walter Kauzmann discovered that nonpolar substances like fat molecules tend to clump up together rather than distributing itself in a water medium, because this allow the fat molecules to have minimal contact with water..

Chromatography of proteins on hydrophobic interaction and ion-exchange chromatographic matrices: mobile phase contributions to selectivity. experiment to show the principles of hydrophobic interaction chromatography (HIC) and their application for separation of two different amylasic fractions from a malt extract. Hydrophobic Interaction Chromatography and Size Exclusion Chromatography Resins. Hydrophobic resins provide high mechanical strength and low backpressure for bioprocessing applications. hYDRoPhobic inTeRAcTion chRoMAToGRAPhY ToYoPeARL Hydrophobic Interaction Chromatography (HIC) is a widely-used technique for separation and purification of proteins and peptides. Hydrophobic Interaction Chromatography, HIC, Media, Reverse Phase Chromatography, RPC. Hydrophobic interaction chromatography -similar to reverse phase chromatography except density of NP functional group on stationary phase is less Ion-exchange chromatography The cyanobacterium Arthrospira platensis is an important source of phycocyanin, which has many commercial applications in foods, cosmetics and pharmaceutics. The image above indicates that when the hydrophobes come together, they will have less contact with water. The experiments are technically simple and are adapted to be included in a weekly course: they may be … The protein typically binds in the native state via hydrophobic groups located on the surface of the protein. They are ideal for protein, polypeptide, enzyme, and nucleic acid purification. Ion-exchange chromatography Polar liquid/ionic solid Molecular charge Size-exclusion chromatography Liquid/solid Molecular size Hydrophobic-interaction chromatography Polar liquid/nonpolar liquid or solid Molecular size/polarity Affinity chromatography Water/binding sites Specific structure Reprinted from ( 8), p. For example, you can select a column to do separations according to a molecule’s hydrophobicity (hydrophobic interaction column), polarity (silica column), or electrostatic charge (ion-exchange column). What is Reverse Phase Chromatography. Property Technique Hydrophobicity Hydrophobic interaction chromatography (HIC) Reversed phase chromatography (RPC) Charge Ion exchange chromatography (IEX), chromatofocusing (CF) Samples are adsorbed to the resin at relatively high salt concentrations and eluted by applying Hydrophobic interactions have a great importance in the biological systems.
