General description
Streptavidin is a crystalline protein synthesized by Streptomycetes.[1]
Application
Streptavidin from Streptomyces avidinii has been used:
- in the pre-functionalization of self-propelled catalytic micromotors[2]
- in the fabrication and modification of hydroxyapatite-chitosan (HA-CTS) nanofilm-coated substrates[3]
- as an analyte to bind biomolecules to the gold-inverted polymer solar cells (Au-IPSC)[4]
Biochem/physiol Actions
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
The sales quantitites 1 mg and 5 mg
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.

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
