Aurion Diagnostics Gold Nanoparticles – Gold Sols – are prepared according to unique production protocols. This provides for sol particles with a narrow size distribution and optimal adsorption properties. A narrow size distribution minimizes variation in your immuno assay and warrants low background levels.
Aurion Diagnostics Gold Nanoparticles – Gold Sols – (solutions of high quality unconjugated gold nanoparticles) have a uniform size and highly adsorptive surface. Aurion Diagnostics Gold Sols provide opportunities for users to prepare conjugates with primary antibodies, ligands and other binding agents via adsorption or covalent binding after functionalization. The gold sols are available in the size ranges 20nm and 40 nm. 40nm being the diameter used in 90% of the lateral flow immunoassays. The smaller diameter for those colorimetric assays were a higher labeling density, the number of gold nanoparticles per amount of antigen, is more important, e.g., in “on-chip” detection.
Aurion Diagnostics Gold Sols are prepared according to a unique protocol, warranting narrow size distribution and reproducible adsorption characteristics.
Typically, the coefficient of variance is less than 12%. Package sizes: 100 ml or 1000ml of high quality gold sol at an OD =1 (20nm OD520nm =1, 40nm OD530nm =1). For larger volumes please inquire.
Gold sols have a guaranteed shelf life of 12 months from the date of quality control analysis.The products should be stored at 4-8°C. Freezing is not recommended.
Detailed instructions for conjugate preparation and evaluation are provided in the package inserts.
