I have long used the kits from Sigma and found them to be extremely reliable.
Call their tech helpline for advice, or reach out to your pathologist for their
preference. I know that "homemade" saves money over kits, but for me, my most
costly and precious resource is my tech time. Save yourself and your techs a
headache and call Sigma-Aldrich.

Hello,
I am seeking some guidance in regards to a peroxidase stain. We have always
used the Kaplow Method to stain peripheral blood smears, and up until recently,
we have had no issues with getting it to work. However, no matter what we try
in recent months, we have not been able to get it to work. Several different
techs have tried it and we have ordered new reagents, but there are no granules
to be seen....
Does anyone have any experience with peroxidase kits? I can see that
Sigma-Aldrich has several available but I'm not sure what to go with....
Any and all help would be greatly appreciated!
Thank you,

For those doing MOHS staining either manually or automatically. How many
staining cups do you really use? Are six enough if there is a running water cup
nearby or do you need more?

What is the Kaplow method? I can't find it in textbooks. A quick Google search
brings up only junk papers indicating that a Kaplov method may use carcinogenic
benzidine (with wrong spelling) as the chromogen.
There are simple, safe and inexpensive methods for histochemical localization
of sites of peroxidase activity.in tissue sections or smears of cells. Buy a
textbook for about $50, read it, and save your lab a fortune in buying special
kits for very simple routine histochemical jobs.
My ten cents-worth. June 2023
