Recombinant Monomeric SA Protein (His tag)

Forms a non-covalent specific complex with biotin. Monomeric streptavidin has unique structural and functional properties that can lead to development of new applications based on the well-known protein–ligand interaction. For example, it allows detection of biotinylated ligands while avoiding target aggregation caused by multivalent binding. Since clustering of biologically active molecules often results in functional changes, monomeric streptavidin can facilitate imaging and tracking studies in live cells by ensuring monovalent biotin binding.

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
