Re. Morris et Gm. Ciraolo, A UNIVERSAL POSTEMBEDDING PROTOCOL FOR IMMUNOGOLD LABELING OF OSMIUM FIXED, EPOXY RESIN-EMBEDDED TISSUE, Journal of Electron Microscopy, 46(4), 1997, pp. 315-319
The authors have found that double etching of epoxy-embedded, ultrathi
n sections with 3% sodium metaperiodate rendered epitope expression co
mparable to that obtained with either saturated or half-saturated sodi
um metaperiodate solutions. In contrast to either of the two more conc
entrated oxidizing solutions, double etching with 3% sodium metaperiod
ate neither bleached the specimens nor generated holes in the plastic
resin.
