SummaryA key step in proteomics the study of proteins function and structure is the purification of proteins. The ability to isolate and purify specific proteins is an essential feature of Modern biochemistry as it allows scientist to study proteins in isolation from other proteins, which greatly aids the under standing of a particular proteins functions. Unfortunately there is no single ideal proteins purification procedure and often the purification of a protein involves several techniques. The main idea behind proteins purification is to select the best techniques to isolate a protein of interest based on differences in its physical properties from other unwanted proteins. The proteins purification aim to cover many of the common techniques used in protein purification.
One of the important aspects of biotechnology is the use of bacteria as living factories to produce genetically engineered proteins know as Recombinant proteins as opposed to purify specific proteins from biological sample is the vast quantities can be produced and scientist can attach affinity tag that allows for rapid and specific purification of the recombinant proteins. The science behind the purification of recombinant proteins with a specialized affinity tag is the use of affinity chromatography. Affinity chromatography involves the attachment of a specific ligand to a solid support or resin. The ligand and will bind the specific tag and all the untagged, non specific proteins are washed from the solid support. The solid support is then treated with an elution buffer that breaks the interaction between the ligand and the tagged recombinant protein. Below are a few example of the more common affinity tags used in science today with information on the tag the ligand the elution buffer.
