Streptavidin and avidin have similar biological properties and are both homotetrameric proteins. Streptavidin, a protein purified from the bacterium streptomyces avidin, has a high affinity for biotin. The binding of biotin to avidin is one of the strongest non-covalent interactions known in nature. Biotin-streptavidin has good tolerance to organic solvents, denaturants, detergents, proteolytic enzymes and pH, therefore, biotin-streptavidin can be widely used in molecular biology and biological in the field of nanotechnology. Based on the strong interaction between biotin and streptavidin, it can efficiently combine with biomolecules and realize the recognition of special molecules, so it is widely used in various biological fields. Alfa Chemistry has an advanced biotechnology team with many years of experience who can design highly efficient biotin-streptavidin systems for efficient biological applications.

Based on the tetrameric conformation of streptavidin, it can selectively bind biotin molecules with high affinity. The main advantage of the biotin-streptavidin system is the high detection sensitivity. The biotin-streptavidin system is also versatile and can be combined with a variety of labels, which can be used in a wide range of immunoassays, such as cell surface labeling, fluorescent cell sorting, and fluorescence detection imaging.
There is a strong interaction between biotin and streptavidin, and streptavidin can be combined with a variety of dyes, which is helpful for target labeling and biological imaging. According to customers' application requirements, the performance requirements of biotin-streptavidin conjugates are different, so researchers need to comprehensively consider the selection of materials in the design process. The biotin-streptavidin system has a very high binding force and has a wide range of applications in the biological field. Alfa Chemistry adopts professional protein coupling technology to covalently link streptavidin to the surface of solid phase carrier, which can be used to efficiently bind biotinylated antibodies, nucleic acids, proteins and other biomolecules.
