Promiscuous In Vivo Biotinylation

The combination of biotin and streptavidin is the strongest known covalent biological interaction and has a wide range of applications in the field of biology. In addition to high-efficiency bioconjugation with avidin, biotin can also be combined with streptavidin and neutravidin to amplify the biotinylation reaction signal and greatly improve the detection sensitivity of proteins. The biological activity of biotinylated proteins is determined by the structure of the protein itself and the way of biotinylation. For special protein samples, a reasonable biotinylation strategy needs to be customized for efficient biotinylation reactions. The strong interaction between biotin and avidin/streptavidin makes it a powerful tool for protein biochemistry. Alfa Chemistry has a professional biotinylation team with many years of experience, and can obtain mixed biotinylated mutant BirA by checking the biotinylation of the mutant protein during expression in E. coli.

Efficient in vivo promiscuous biotinylation with ultrahigh sensitivity

In biochemistry, biotinylation refers to the process of covalently attaching biotin to proteins or other biomolecules, which can be carried out by chemical biotinylation or enzymatic biotinylation. The biotinylation reaction is fast, efficient and has strong anti-interference ability. Biotin Ligase (Biotin Ligase) is encoded by the BirA gene, which can activate biotin to form biotinyl-5'-adenylic acid, and transfer biotin specifically to biotin receptor tagged proteins (such as AviTag fusion protein) , to biotinylate tagged proteins, and can also be used as a biotin operon blocker.
