Dear Garry and All,<br>
We have used the method of Dominici (1902) as quoted in Peter Gray's
Encyclopaedia to demonstrate eosinophils.<br><br>
It uses an aqueous solution containing 0.5% Eosin Y and 0.5% Orange G
for 7 minutes, rinse in water<br>
then counterstain with 0.5% aqueous Toluidine Blue O for
20seconds.<br><br>
The other simple way to make eosinophils stand out is to do a H+E stain
but overstain with Eosin and then differentiate the eosin until other
structures, such as muscle or collagen, are very pale pink and the the
eosinophils will be prominent. The Eosin solution we use contains Eosin Y
and Erythrosin B.<br>
Eosinophils are very satisfying to stain, particularly horse
eosinophils.<br><br>
Regards,
Laurie.<br><br>
