GoldEnhance - Model EM Plus -Deposit Metallic Gold

Deposit metallic gold to enlarge ultrasmall gold nanoparticles for EM - Use it with Nanogold®! Slow enhancement for an easy control of particle size. Great for SEM: Gold gives a much better backscatter signal than silver. Low background - No autonucleation for 40 minutes. Neutral pH for best ultrastructural preservation. Permanent staining: does not fade. Resistant to osmium tetroxide etching: may safely be used before osmium tetroxide staining with no need for gold toning or other protective treatments. Gold is stable in the oxidizing agent OsO4; silver would dissolve. Compatible with physiological buffers and other halide solutions --these would precipitate silver. Can be used for specimens on metal surfaces (e.g. cell culture substrates). Low viscosity. Light insensitive. Mix-and-use.
