Promiscuous In Vitro Biotinylation

Biotinylated proteins can be purified by high affinity avidin or streptavidin. Biotinylation can be carried out chemically and biologically. Biotin ligase can be used to catalyze biotinylation reactions and is also an inhibitor of biotin induction. A common biotin ligase is the BirA enzyme in E. coli that recognizes protein interactions. The way of biotinylation will significantly affect the results, and each protein is unique, so it is of great significance to design a unique and efficient biotinylation strategy. The BirA enzyme is a robust protein that retains its essential activity even at room temperature. Since its establishment, Alfa Chemistry has insisted on being customer-centric, and can provide customized services according to customer needs. Alfa Chemistry has experienced researchers who can select suitable promiscuous bioreceptors for in vitro biotinylation reactions. We provide efficient in vitro promiscuous biotinylation service strategies that are widely applicable to protein purification and immobilization.

About biotin ligase

The binding between biotin and streptavidin or avidin is one of the strongest known non-covalent biological interactions and is widely used in biological research and biotechnology. Protein labeling with biotin is an efficient method for protein capture, immobilization and functionalization of conjugated biomolecules. BirA enzyme is an E. coli biotin ligase that performs site-specific biotinylation of lysine side chains within the 15 amino acid acceptor peptide. BirA enzyme is an important reagent for biotinylation reactions, which can recognize biotinylated proteins at specific residues in the sequence.
