RE: blueing tissue sections

Well, never had trees from the lithium, but you might try ammonium hydroxide
- a few drops or your tissue will fall off though! Bless your heart for
doing the work yourself! It'll be good training - it really will! J:>)

	Subject:	blueing tissue sections

	I am a learning-by-doing-histotechnologist (I am a resident (medical

	doctor) in pathology and now have to do my research work by myself,
	because my technician is pregnant)and I need some advice:

	what can I use instead of hot running tap water for blueing the
	sections after Mayer's hematoxylin? Our hot tap water is really ugly

	brown and it takes "hours" until it is clean.
	Today I tried 0.5% lithium carbonate for 30 sec. The colour is very
	however I have got a lot of "arbored" precipitates (like small
trees, if
	you understand what I mean) on top of the tissue, I washed and
	with buffer, with dist. water, with dist. water and Triton X, but I
	not get rid of this precipitates. What is the problem with lithium
	carbonate as a blueing solution? Or may be it is the concentration?
	Any suggestions what to use instead?

	thank you for your help,
