Description

Ready to Use CdSe/ZnS Qdots Nanoparticle Streptavidin Conjugate for Lateral Flow

Our Streptavidin CdSe/ZnS Quantum Dots (QDs) conjugate is manufactured using special conjugation technology and functonally tested by lateral flow. We have coated our high quality nanoparticles with a proprietary surface coat that covalently binds the biotin forming ultra stable conjugates. The resulting Streptavidin CdSe/ZnS QDs  can irreversibly bind biotin.

fluorescent broad range UV light excitation range of 100nm to 400nm, 655nm emission

Highly stable and uniform Streptavidin CdSe/ZnS Qdots in a Ready To Use format
