Re: Luxol Fast Blue (LFB) and OCT
David,
Either you or your boss need to read up on the basics
of myelin staining. There are 3 different luxol
fast blue dyes: ARN, G and MBS. Their similarities
are their blueness and their being salts of coloured
hydrophobic anions with hydrophobic cations. Such
salts dissolve in alcohol but not in water. The
technology of using these dyes to stain myelin,
which is a hydrophilic lipid, depends critically
on both the actual dye used and the mixture of
solvents from which it is applied.
It is possible to get spectacular myelin staining
with "luxol" dyes, but why use compounds of
uncertain identity, some of which haven't been
manufactured for many years? Myelin can be
stained easily with inexpensive non-secret dyes
that have been available for 100 years. It's
all in the textbooks: recent ones and ones that
pre-date the introduction of a "luxol" blue
by Kluver & Barrera in 1953.
