Descrizione generale
Streptavidin is a crystalline protein synthesized by Streptomycetes.
Applicazioni
Streptavidin from Streptomyces avidinii has been used:
- in the pre-functionalization of self-propelled catalytic micromotors
- in the fabrication and modification of hydroxyapatite-chitosan (HA-CTS) nanofilm-coated substrates
- as an analyte to bind biomolecules to the gold-inverted polymer solar cells (Au-IPSC)
Azioni biochim/fisiol
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.
Confezionamento
Bottomless glass bottle. Contents are inside inserted fused cone.
The sales quantitites 1 mg and 5 mg
Definizione di unità
1 U corresponds to the amount of protein which binds 1μg (+)-biotin at pH 7.5
Risultati analitici
Binding capability: Streptavidin binds one molecule of biotin per subunit. Comparison of biotin binding and absorbance measurements indicates that ≤5% binding sites are occupied.

Complementary assays are required to comprehensively map complex biological entities such as genomes, proteomes and interactome networks. However, how various assays can be optimally combined to approach completeness while maintaining high precision often remains unclear. Here, we propose a framework
