blueing trees resolved
From: | Heike Grabsch <h.grabsch@uni-koeln.de> |
After a lot of trials and experiments with no conclusive result I just
throw away my Mayer's Hämalaun and used fresh one. Because I was in a big
hurry I forgot to add the recommended drops of ammonia - and no more
"blueing trees"! So I made one more experiment and added a couple of
drops of ammonia : and there they are again. So, I conclude from this,
that the concentration of the ammonia is critical regarding precipitates
on tissue sections and that probably my understanding of adding "some
drops" as recommended was incorrect and I added too many drops?
Thank you all for your help and especially John for the comments on
"Haema-what".
