Biotinylated Protein Service

The biotin-streptavidin system is a system that can amplify biological signals, so it can be widely used in biological immunology. There is a high affinity between biotin and streptavidin, which can be organically combined with luciferin, enzymes, isotopes and other immunolabeling techniques to further improve the specificity and sensitivity of immunity. Biotin is a component of complex vitamin B2, which has high affinity and binding force with chicken albumin, avidin, mycoprotein and streptavidin. Both avidin and streptavidin are tetrameric proteins, and their binding force is the strongest non-covalent interaction known in nature. The interaction between biotin and avidin can be used in protein purification, detection, immobilization, drug targeting and protein structure analysis.

The Services

Alfa Chemistry can provide professional biotinylated protein labeling services, has a comprehensive protein database, and can cover a rich protein library. With years of technical accumulation, our scientific researchers can carry out industrial optimization, and insist on meeting customer needs with high-quality and low-cost products. We can efficiently and quickly complete biotinylated protein labeling services according to customer needs, including but not limited to:

• Biotinylated protein labeling
• Recombinant protein biotin labeling preparation service

Methods for protein biotinylation

• After the recombinant protein is purified, the biotinylated protein is obtained by chemical biotin labeling, and the carboxyl group of biotin is usually used for professional chemical modification. This method may cause the inactivation of some proteins and is non-specific.
• Through the fusion expression of Avitag and the recombinant protein, the biotin tag is biotinylated in vitro, so as to realize the biotinylation of the recombinant protein. This specific site-specific modification has little effect on protein activity, and the yield is high and the product is specific.

Advantages of biotinylated proteins

• Quality control: The biotinylated proteins we provide are subject to strict activity assays, which can confirm that the performance of the protein will not be affected during the entire process
• Rich drug targets: We provide a variety of rich protein systems covering all drug targets, and can work with biotin-modified proteins efficiently and quickly according to customer needs
• Competitive price: With years of technology accumulation, we actively optimize the process and ensure quality improvement while controlling costs
