Streptavidin from Streptomyces avidinii, affinity purified, lyophilized from 10 mM potassium phospha

Descriptions

Analysis Note

Binding capability: Streptavidin binds one molecule of biotin per subunit. Comparison of biotin binding and absorbance measurements indicates that ≤5% binding sites are occupied.

Application

Streptavidin fromStreptomyces avidinii has been used:in the pre-functionalization of self-propelled catalytic micromotorsin the fabrication and modification of hydroxyapatite-chitosan (HA-CTS) nanofilm-coated substratesas an analyte to bind biomolecules to the gold-inverted polymer solar cells (Au-IPSC)

Biochem/physiol Actions

Streptavidin is a biotin binding protein and has the ability to bind four molecules of biotin. The biotin binding pocket of streptavidin helps to interact with biotin. It can be used to enhance protein binding and multimerization.

General description

Streptavidin is a crystalline protein synthesized by Streptomycetes.
