Re: hemoglobin stain

From:Barbara Stancel <>

Jill,  Here is a copy of our procedure.  It is very simple and fairly quick 
when you heat the solution in the microwave. We perform this procedure about 
twice a week, so we keep a stock solution of the Alizarian Red S.  Give us a 
buzz if you have any questions.

We also have plenty of controls if you need one.
