Biotinylation Service

Biotinylation is the process of covalently linking biotin to your protein or antibody. Due to its small size, biotin is a popular tag and has little effect on the immune reactivity of antibodies. Biotin can bind to streptavidin and avidin with extremely high affinity, and is used to improve detection sensitivity in many immune procedures. CD BioSciences is committed to providing high-quality biotinylation service to major domestic and foreign pharmaceutical companies. As a life science service expert around you, we can provide one-stop or highly customized services according to the specific requirements of customers. Please contact us directly and we will get back to you as soon as possible.

Overall solution

Biotin labeling is commonly used for non-radioactive labeling and purification of proteins and other target molecules. Biotin labeling takes advantage of the unusually strong interaction between biotin (vitamin H) and avidin or streptavidin. The affinity of biotin for avidin or streptavidin is one of the strongest known non-covalent interactions between protein and ligand, and its dissociation constant (Kd) is about 10-15. In addition, this interaction is resistant to high or low pH, high salt concentration, extreme temperatures and denaturants. These properties of the biotin-avidin interaction make it useful for purification and/or detection of proteins of interest. CD BioSciences has many proteins that have been chemically used through various reaction sets and the use of AviTagTM technology enzymes to facilitate biotin labeling.
