If you make a cell block from Saccomano's fixed material, you must remove
all the carbowax from the material with several washing of 95 % alcohol
followed by several in PBS, otherwise you get poor infiltration with gelatin
or agar and traces of alcohol also impede.
Because of the large amount of handling you may also get damage so be gentle
with your centrifuge.
