2017-03-29 Thread Teri Johnson via Histonet
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.

Hi Jackie, The ethanol we use is denatured with a lot of stuff that can include methanol, MIBK, Toluene, and ethyl acetate , and our nuclear stains are crisp and sharp. I would start looking at fixation first, followed by their H&E stain procedure and reagents. Teri Johnson, HT(ASCP)QIHC

think that cutting temperature is too cold when your tissue sample shatters when sectioning (depending too on the thickness). If you can rub your thumb across it and you get a few decent sections, the warming of the specimen likely explains it. Teri Johnson, HT(ASCP)QIHC GNF Histology Lab
