Protein expression and purification may refer to: Protein production, the process of generating some quantity of a specific protein using living organisms; Protein purification, the process of separating a specific protein from a mixture of proteins and other molecules; Protein Expression and Purification, a peer-reviewed scientific journal on ...
The protein manufacturing cost remains high and there is a growing demand to develop cost efficient and rapid protein purification methods. Understanding the different protein purification methods and optimizing the downstream processing is critical to minimize production costs while maintaining the quality of acceptable standards of homogeneity. [2]
Protein production is the biotechnological process of generating a specific protein. It is typically achieved by the manipulation of gene expression in an organism such that it expresses large amounts of a recombinant gene .
FLAG-tag can also be used in the isolation of protein complexes with multiple subunits, because FLAG-tag's mild purification procedure tends not to disrupt such complexes. FLAG-tag-based purification has been used to obtain proteins of sufficient purity and quality to carry out 3D structure determination by x-ray crystallography.
Additionally, it can facilitate more purification steps through direct secretion into the culture medium, and can easily be scaled up because of its ability to non-specifically secrete these proteins. To date, B. subtilis has been used to successfully study different biological mechanisms including metabolism, gene regulation, differentiation ...
Protein Expression and Purification is a peer-reviewed scientific journal covering biotechnological research on protein production and isolation based on conventional fractionation as well as techniques employing various molecular biological procedures to increase protein expression.
