Key Features
- Monodisperse particles with spherical and uniform morphology to support lot-to-lot consistency.
- Particle-size CV below 8%.
- Gold conjugation at 40 OD can reduce antibody reagent consumption by up to 80% under the compared process.
- High-concentration conjugation can reduce processing volume, centrifugation time and equipment requirements.
Process Comparison
The following data illustrates a conjugation-process comparison for a SARS-CoV-2 assay at a production scale of approximately 1 million tests. Actual results may vary depending on assay design and process conditions.
| Gold Nanoparticles | Conjugation Volume | Centrifugation Time | Antibody |
|---|---|---|---|
| Ultra-Concentrated Gold (100 OD) | 1.7 L | 1–2 h | 100–250 mg |
| Conventional Gold (1 OD) | 68 L | 2 d | >350 mg |
Storage & Stability
Store at 2–8°C. Shelf life is 12 months under the recommended storage conditions.
Intended Applications
Suitable for lateral flow assay development, gold conjugation, rapid-test manufacturing, assay optimization and production-scale evaluation. Final performance should be validated with the intended assay configuration, biological reagent and sample matrix.
