Allgemeine Beschreibung

Streptavidin is a biotin-binding protein that is obtained from Streptomyces avidinii. It is resistant to extreme temperature, pH, detergents and proteolytic enzymes. Streptavidin has a molecular weight of 60kDa and exists as a homotetramer.

Anwendung

Streptavidin from Streptomyces avidinii has been used-
  • for blocking of the AFM (atomic force microscopy) tip, during the measurement of unbinding forces in the avidin-biotin system
  • for coupling of anti-HA (hemagglutinin) antibodies during cell free synthesis and assembly of proteins on a biochip
  • for the coating of the gelatin flow phantoms to eventually determine the feasibility of IVUS (intravascular ultrasound) transducer for (biotinylated) microbubble-based drug delivery
  • to immobilize proteins and oligonucleotides

Biochem./physiol. Wirkung

Streptavidin is an antibiotic that functions by binding to and depleting the essential vitamin biotin from the surrounding environment. Because of its unique properties, streptavidin has found various applications in biological studies, including immunotherapy, immunoassays, hybridization assays, lymphocyte activation, antigen localization and affinity chromatography.

Einheitendefinition

One unit will bind 1.0 μg biotin.

Physikalische Form

Lyophilized from 5 mM potassium phosphate buffer
