Dear Ian ,
any of the Romanowsky stains will work well on sections ie. Giemsa,
Leishman, or wrights but you will need a pH of 6.4 or even 6.0 rather than
the 6.8 Haematology use. Your routine H&E will also do extremely well if you
use a buffered eosin pH5.2-5.4 as will also EA50 from Cytology which has the
same pH. If you want a recipe for the Eosin Alc. or Aq. let me know.
Regards Mike (Downunder)

>STAIN.
> Phenol. = 1 g. (Melt in a flask under hot water.)
> Chromotrope 2R. = 0.5 g. (Add to the melted phenol and mix.)
> Distilled water. = 100 ml. (Dissolve the dye sludge.)
> The stain keeps for up to 3 months.

>METHOD.
>1.) Bring sections to water.
>2.) Counterstain nuclei with Haemalum. (If required - looks good.)
>3.) Blue in running tap water.
>4.) Carbol Chromotrope. = 30 mins.
>5.) Wash in running tap water.
>6.) D.C.M.

>RESULT.
> Eosinophil granules = Bright red.
> Nuclei. = Blue/black.
