Streptavidin CdSe/ZnS Quantum Dot Conjugates — Ready-to-Use Fluorescent Nanoparticles for Lateral Flow Assays
Available in Tetrameric or Monomeric Streptavidin Formats
Attogene’s Streptavidin CdSe/ZnS quantum dot (QD) conjugates are engineered for fluorescent lateral flow and related assay platforms requiring stable, high-affinity biotin recognition. Conjugates are produced using a controlled covalent functionalization process and undergo functional verification in lateral flow assay conditions to ensure consistent signal performance and reproducibility.
Each nanoparticle incorporates a proprietary surface chemistry designed to maintain colloidal stability, preserve fluorescence intensity, and support robust biotin–streptavidin interactions under typical assay workflows. The formulation is supplied at a ready-to-use concentration to minimize preparation variability and accelerate assay development and routine implementation.
