Protein separation chromatography
WebbChromatography Definition Protein purification employs multiple chromatography techniques that separate products according to differences of their properties. Tagged proteins are convenient to be handled by affinity chromatography, which is designed to capture the target protein based on biorecognition of the protein tag. WebbIn the first step, a recombinant protein mixture is passed over a chromatography support containing a ligand that selectively binds proteins that contain an affinity-tag sequence (typically His or GST). Contaminants are washed away, and the bound protein is then eluted in pure form. Affinity tags have different advantages.

Choice of a starting material is key to the design of a purification process. In a plant or animal, a particular protein usually isn't distributed homogeneously throughout the body; different organs or tissues have higher or lower concentrations of the protein. Use of only the tissues or organs with the highest concentration decreases the volumes needed to produce a given amount of pu… Webb1 okt. 2010 · The availability of robust and highly efficient separation methods represents a major requirement for proteome analysis.
