• Cost-effective
$100.00 – $700.00
Overview
The high purity, stability, and bare surface of i-colloid 40 nm gold nanoparticles allows efficient conjugations and reproducible conjugate performance in lateral flow immunoassays. IMRA’s laser-ablation process allows Au40 to be a cost-effective solution for assay development.
Features and Advantages
• Stable without capping agents or surfactants
• Each batch QC tested for consistent performance
• High contrast with Gold-Platinum in dual-color assays
• Laser-made for highest purity
