In Stock & Ready to Ship

Highly stable and uniform Streptavidin CdSe/ZnS Qdots.  The quality and performance of a conjugate is critical to successful lateral flow test manufacturing.  Our products are produced in a state-of-the-art manufacturing facility that enable rapid turnaround times while ensuring batch to batch consistency and reliability.


Europium Chelate Microspheres Nanoparticle Streptavidin Conjugate for Lateral Flow

Our Streptavidin Europium Chelate Microspheres 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 Europium Chelate Microspheres  can irreversibly bind biotin.
