[Histonet] Re: Neutral mucus stain

From:"Andrew Kennedy"

Hi Nancy,


Is this stuff still positive in a Diastase PAS? 

Might it be a glycoprotein or a glycolipid? 

A High Iron Diamine stain will distinguish glycoproteins from other

Try a Sudan fat stain or an Oil Red O for glycolipids

Does anyone know of a diagnostic stain for neutral mucus?  OR does anyone
know a good control tissue we could use?  We have identified a PAS +, alcian
blue negative, toluidine blue orthochromatic, carmine red slight positive
(and we know it's not glycogen) exocrine gland secretion (in an amphibian)
and think it is neutral mucus.  IS there anything else we can try that isn't


thank you much.
