Hi Mariam,
Mayer's is a progressive hematoxylin. Therefore you should increase your time
in the stain to get a deeper color. You might try 10 or 20 minutes and see what
works best for you.
You can do your bluing in tap water or even buffer solution rather than
ammonium hydroxide if you prefer.
Dr. Richmond,
Thank you for all your contributions to the histonet over the years. I would
have loved working with you. I know I loved learning from you.

Hi Bernice,
Likely there is something in your TUNEL procedure that is causing a problem
with histochemical nuclear staining. If it isn't the pre-treatment, it might be
the DAPI. After all, they do bind the same structures, and the DAPI might be
winning that competition.
