Re: Help with clarification of "Lake"
|From:||Bryan Llewellyn <firstname.lastname@example.org> (by way of histonet)|
It usually makes very little difference whether you use a rack or a coplin
jar (or a slide mailer, petri dish or bench top). I have used all of these
successfully over the years.
Incidentally, you refer to a lake for *cytoplasmic* staining. This would
likely involve basic tissue components. Most lakes stain acid tissue
components such as nuclei (DNA). If you have a specific method in mind,
perhaps you could mention it by name and give the procedure you are using.
There is really insufficient information to make reasoned comments.
