Gold Nanoparticles – Gold Sols

Description

AURION Gold Nanoparticles Gold Nanoparticles – Gold Sols – have been developed for conjugate preparation via the classic direct adsorption method. Gold Nanoparticles – Carboxyl Functionalized – have been developed to facilitate conjugating gold nanoparticles to molecules that cannot be conjugated via the classic direct adsorption method. The product is especially suited for covalent conjugation of small ligands. Gold Nanoparticles – Gold Sols 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. Introduction 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 Nanoparticles – 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 Gold Sols are prepared according to a unique protocol, warranting narrow size distribution and reproducible adsorption characteristics. The gold sols are available in the same size range as the Conventional Immunogold Reagents: 6, 10, 15 and 25 nm. The particle population is monodisperse and thus shows minimal size variation and overlap. Typically, the coefficient of variance for the 6 and 25 nm particle size sols is less than 12%, whereas the 10 and 15 nm size sols show less then 10% variation. Actual lot specifications (size, variation and expiry date) are indicated on the accompanying package insert. Package size: 100 ml of high quality gold sol at an OD520nm of approximately 1. Storage 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. Application Instructions Detailed instructions for conjugate preparation and evaluation are provided in the package inserts.
