Description

Streptavidin is a 52.8 kD tetrameric protein obtained from Streptomyces avidinii. It binds to biotin with a very high affinity and is one of the strongest interactions in nature with a dissociation constant of 10^-14 mol/L. It is used in a wide range of applications including ELISA, flow cytometry, molecular biology, and bionanotechnology.

Formulation

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.06 microg per million cells in 100 microL volume. It is recommended that the reagent be titrated for optimal performance for each application.
