Labeling Enhancers for EM, LM and Blots


Step 1: High Resolution Labeling

Label your proteins and peptides
with our ultra-small gold nanoparticle labels

...Their tiny size will give you super-specific targeting,
and incredible penetration (up to 40 µm into tissues!)

Step 2: Enhancement for Imaging

Enlarge our ultra-specific labels
with our Silver or Gold

See everything clearly, using our easy kits for EM, LM or blots
--Get amazing images that journals will love!

Buy nowGoldEnhance™ Gold Enhancement Kits
The next generation of labeling enhancement, solving some issues with silver developers.



Better than silver in many cases:
  • May safely be used before osmium tetroxide staining (silver is dissolved by the oxidizing agent O4; gold is stable)
  • Lower backgrounds than silver in many cases; autonucleation minimal even after 1-2 hours
  • For SEM, gold gives a much better backscatter signal than silver
  • Compatible with physiological buffers (silver precipitates with chloride ion, as in PBS buffer; gold does not)
  • Reaction is less pH senstitive than silver, and GoldEnhance™ is near neutral for best structural preservation of biological samples (many silver enhancers have a pH of 3-4)
  • Excellent shelf life
  • Low viscosity for easy and accurate mixing of components
