High Sensitivity Gold Conjugation Kit for Lateral Flow

Imagine an optimized system with time-after-time consistency that provides increased sensitivity and saves you time and money!

Benefits of the kit include:

  • Pre-validated consumables eliminate the risk of purchasing non-compatible reagents, saving weeks to months of unnecessary troubleshooting
  • Increase your assay sensitivity up to 20-fold with 150 nm gold nanoshells compared to 40 nm gold* nanoparticles
  • Reduces antibody costs up to 65% compared to physisorption
  • Saves time by reducing the number of conjugations necessary to find optimal antibody pairs
