Dear Carol,
if you follow the application of Alcian Blue with 0.3-0.5% Sodium Carbonate
the colour will be insoluble in all subsequent treatments.
You can use either haematoxylin, but as a general rule the weaker Mayer's
will not overstain or detract unduly from the overall slide. If you use
Harris - keep it very short eg.20secs. You will get a much more contrasting
picture if you use Kernechtrot Red with a very cear background. Saffranin O
and Neutral red may also be used but the picture is not as precise, with
differentiation sometimes being a problem in inexperienced hands.
