Datasheet (RG)

For most applications the detection of ultra small gold particles in electron microscopy requires a particle enhancement procedure. Danscher’s method has always been the standard for this purpose and for a long time attempts to improve the features of Danscher’s system met with only limited success.

The goal in the development of AURION R-Gent SE-EM was to create a new system with enhancement efficiency and homogeneity at least comparable to Danscher’s method, but with reduced acidity and light sensitivity. In addition, the reagents should have low viscosity for the suitability in pre-embedding immunogold labeling.

Introduction
The silver enhancement reaction is a gold particle-catalyzed reduction in which silver ions are reduced to metallic silver with a photographic developing compound as the electron source. In addition in many applications a “protective colloid” is added to the enhancement solution to limit diffusion of reagents to the gold particle surface, thus providing a means for controlling particle growth.

Product Description
AURION R-Gent SE-EM is a high efficiency silver enhancement reagent for electron microscopy. It intensifies the gold particles by homogeneous deposition of metallic silver on the particle surface. The resulting electron dense signal is easily detected and is compatible with heavy metal counterstaining. The reagent has extremely delayed auto-nucleation and can be used under standard laboratory light conditions. It also has low viscosity, which is especially advantageous for pre-embedding immunogold applications. The enhancement mixture has a pH of 8.1-8.2.

AURION R-Gent SE-EM has been tested intensively for the enhancement of AURION Ultra Small Immunogold reagents.
