Protein Tag: N-His
Accession: 6ZYT_AAA
Background: 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.
Bio Acitivity: Not validated for activity
Sequence: Ala 17-Lys 130
Purity: > 95% as determined by reducing SDS-PAGE.
Formulation: Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 150mM NaCl, pH 8.0.
Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.
Endotoxin: < 10 EU/mg of the protein as determined by the LAL method.
Calculated MW: 12.5 kDa
Observed MW: 13-15 kDa
