  • After dehydratation in a growing gradient of ethanol, 5 min for each step: 30, 50, 70 and 95\%, impregnation steps and inclusion were performed in Epon finally polymerized at 60°C for 48 h. 60-80 nm sections were obtained using an ultramicrotome RMC-MTX (Tucson), and contrasted with uranyl acetate and lead citrate.
