Biotinylated Expression, Purification and Characterization

In biochemistry, biotinylation refers to the process of covalently attaching biotin to proteins, nucleic acids, or other biological macromolecules. The biotinylation reaction is fast, efficient and insensitive to interference (unaffected by heat, pH and proteolysis). Biotinylation methods include chemical biotinylation and enzymatic biotinylation. BirA is a biotin ligase that catalyzes the covalent attachment of biotin to specific lysine residues of BAP fused to recombinant proteins. Biotinylation of specific sites can be achieved through the expression of recombinant proteins. The presence of endogenous BirA in E. coli improves purification and near homogeneity, and co-expression increases biotinylation efficiency. Alfa Chemistry provides a wide range of biotinylation-related services, improves service provision, focuses on a wide range of biotinylation strategies, and insists on meeting customer needs with high-quality services.

Efficient purification of biotinylation is of great significance to the study of biology

Biotinylation refers to the process of covalently attaching biotin to biomacromolecules (proteins or nucleic acids, etc.), and is involved in important physiological processes. The biotinylation reaction has the advantages of fast response, high efficiency, and strong anti-interference ability. Proteins participate in important processes of organisms and are the basis of life activities. With the deepening of the fields of molecular biology, structural biology and genomics, more and more biotinylation studies are carried out based on essential research. The most basic requirement for biotinylation is highly purified, biologically active and stable proteins. It also requires accurate characterization of protein interactions, which is of great significance for a detailed understanding of molecular biology.

The significance

• Study the essence of life, understand the laws of life activities, and reveal the significance of biotinylation
