AURION R-Gent SE-LM

R-Gent SE-LM Silver Enhancement Reagents

The AURION R-GENT SE-LM components constitute a Silver Enhancement Reagent which increases the average gold cluster or particle size by deposition of metallic silver facilitating detection at the light microscopical level. The generated brown-black signal is also easily detected in bio assays and is compatible with counterstaining in light microscopy. AURION R-GENT SE-LM has been tailored for the enhancement of AURION Ultra Small Immunogold reagents and is equally suited for the larger sized particles in the AURION Conventional Immunogold reagents.

For enhancement, equal amounts of the DEVELOPER and ENHANCER are mixed well and applied to the specimen. The enhancement mixture is easy-to-use, exhibits extremely delayed auto-nucleation and can be used under standard laboratory light conditions. Typical enhancement times are between 15 and 30 minutes. Auto-nucleation becomes visible only after 40-60 minutes. Light microscopical specimens may be counterstained according to standard procedures. The enhancement mixture has a pH value of 8.3-8.5.

AURION R-GENT SE-LM is available as a kit in two unit sizes (2 x 30 ml or 2 x 250 ml) and consists of a separate DEVELOPER and ENHANCER. The supplied amounts accomodate 600 and 5000 LM specimens respectively at 100 μl/specimen, or 60 and 500 bio assay specimens at 1 ml/specimen. The reactivity is tested on dot-spots and the absence of autonucleation is monitored by spectrophotometric techniques.
