The interaction between biotin and streptavidin represents one of the strongest non-covalent interactions known today. Labeling the target protein with biotin provides a convenient way to mediate protein detection through addition of streptavidin labeled with e.g. HRP, alkaline phosphatase, fluorescent probes etc. Alexotech provide custom based biotin-labeling of your protein of interest.
