Leírás

Általános leírás

Streptavidin is a crystalline protein synthesized by Streptomycetes.

Alkalmazás

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)

Biokémiai/fiziológiai hatások

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.

Kiszerelés

Bottomless glass bottle. Contents are inside inserted fused cone.

The sales quantitites 1 mg and 5 mg

Egység definíció

1 U corresponds to the amount of protein which binds 1μg (+)-biotin at pH 7.5

Analízis megjegyzés

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