>>Hi,
You can make a stock solution of AEC: 0.4 % in dimethylformamide
(Sigma A-5754).
Incubatie your preparations with a mixture of:
0.5 ml AEC stock
9.5 ml 0.05 M Sodiumacatate pH 5.0
0.1 ml 3% H2O2 (hmmm.... underscript still not possible)
Filter this solution before use.
Embed your preparations in a water containing mediumn like aquamount or
glycerol 50%.
Succes
