In case you want to look it up yourself, it is sometimes
called

Muller Colloidal Iron
Mowry Colloidal Iron
Muller-Mowry Colloidal Iron
Hale Colloidal Iron
or "any of the above names" dialysed iron 


Basically, you are inserting iron into mucin, then
doing the Prussian Blue iron stain to demonstrate the
iron you just put into the mucin. Usually,
nuclear fast red is the counterstain, but 
others can be used.

Basically stains the same thing as Alcian blue.
More sensitive than the alcian blue, so will 
demonstrate smaller, weaker deposits. Also seems
to be a more intense, slightly deeper blue than 
alcian blue. Takes a longer time than alcian blue, 
and some of the connective tissue is stained a 
little more than with alcian blue.

If  your lab does the iron stain (Prussian blue), 
then the only extra reagent you need is ferric 
chloride.

Sorry I don't know of any where in S. CA that
you can send it out to, but I'll send you our
procedure, if you would like. Let me know.
