To prepare a high quality (immuno)gold conjugate it is important to have particles with uniform size and highly adsorptive surfaces.
The Aurion gold sols are prepared according to unique production protocols. This provides for sol particles with the same narrow size distribution and adsorption properties as employed in the Conventional Immunogold Reagents.
The preparation of conventional gold reagents is based on gold particles with a diameter suited for direct electron microscopic visualization. Aurion offers a range of Conventional Immunogold Reagents which cover the majority of approaches in transmission and scanning electron microscopy.
Aurion Gold Sols (solutions of high quality unconjugated gold particles) provide opportunities for users to prepare conjugates with primary antibodies, ligands and other binding agents with the same particle characteristics as in the Conventional Immunogold Reagents.
Product Description
Aurion ST-US is based on Ultra Small atomic gold clusters (number of atoms/cluster <30) having an average diameter of approximately 0.8nm. The Ultra Small particles have been stabilized with Bovine Serum Albumin fragments which may be covalently bound to macromolecules by e.g., glutaraldehyde cross-linking.
Package size: 20ml of Bovine Serum Albumin stabilized Ultra Small gold at a concentration of approximately 5x10E13 particles/ml
Storage
AURION 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.
