Streptavidin Quantum Dots

Streptavidin Quantum Dots are a group of streptavidin conjugated, water soluble core/shell quantum dots. Streptavidin is covalently coupled to the surface of quantum dots and makes most of the biotin binding sites sterically available for binding of biotinylated molecules such as protein, DNA and peptide. It's highly recommended that the monobiotinylated molecules which have only one biotin linked to each biomolecule, is used to link to Streptavidin Quantum Dots. Otherwise,Streptavidin Quantum Dots tends to aggregate.

Features:

• Narrow emission peak
• Wide choice of emission colors
• Low non-specific binding
• High colloidal stability

Applications:

• Immunoassay
• Multiplexing
• Tissue Imaging
