Streptavidin CAS NO.9013-20-1

In terms of structure, the 127AA core structure of streptavitin containing SA exists in the form of homologous tetramers, each mole of tetramer molecules can bind four moles of biotin molecules, and the international standard specific activity is 12-15IUmg. This property, combined with biotin coupled antigenantibody detection technology, makes it widely used in the amplification of ELISA detection signals in immunology. In addition, this product can be mainly used for the surface coating of immune microporous plates, immune chromatography cellulose nitrate membranes, gene chips, protein chips, rapid fixation of biotinized antigens, antibodies, nucleic acids and other substances. It can also be used for coupling NHS magnetic beads, resin microspheres, as luminescent diagnosis, biotinized substance separation, magnetic test strip immunochromatography and other applications.
