Abstract:
In this report we present a staining method in which gold chloride is used to enhance the size of gold colloids. We show the utility of this technique when used in conjunction with small gold colloids, i.e., 5 nm, 4 nm, and 2.6 nm. Post-embedding staining of epoxy-embedded, gold-labeled mouse LM fibroblasts showed that staining with 0.1% gold chloride facilitated the visualization of the smallest gold colloids.
