Molecular Separation / Molecular  Separation - Affinity chromatography 

 

Background Information: A major goal in the biochemistry or molecular biology laboratory is the isolation of a specific protein from complex mixtures. Such isolation procedures often involve several fractionation steps with the effectiveness of each step monitored by electrophoresis. Chromatography is a type of fractionation similar to electrophoresis in that proteins separate from each other as they are passed through a matrix. With chromatography, however, solvent flow (by gravity, pressure or capillary action), not an electric field, carries the proteins through the matrix. The separation occurs because proteins interact with various matrices in different ways. Chromatography matrices are designed to exploit the physical and chemical interactions of a protein of interest. For example, acidic proteins will interact with a basic matrix to a greater extent than basic or neutral proteins so a basic matrix can be used to separate acidic proteins (which will interact with the matrix and be retained) from non-acidic proteins (which will flow through the matrix). The acidic proteins retained by the matrix can then be removed or eluted by disrupting their interactions with the matrix. The major limitation of most types of chromatography is the lack of specificity for only one protein, for example a basic matrix willretain all acidic proteins to various extents and not just the specific protein of interest.
