Dear Dr. Kiernan and Barbara, and colleagues,
I am also very interested in collagen staining using blue dyes for better contrast for image analysis. For now we use picro-sirius red overnight without counterstaining. Could you send me detailed protocol, please.I mean: time of incubation, wash, differentiation ect.As well could you give me a name of Dr. Kiernan book and where I can buy it.
Thank you at advance.

Dear Linda K Bauer,
Nobody has replied to you on Histonet for about
a week, so a few speculative comments from a
non-user of the X-gal technique may be better
than nothing at all. This reply has three parts.
1. How can you have "excess nonspecific X-gal
stain"? The substrate (X-gal) is hydrolysed by
beta-galactosidase and one of the products of
hydolysis, "X" (which is short for
5-bromo-4-chloroindoxyl), is rapidly oxidized (by
the ferricyanide ions in the incubation medium) to
an indigoid dye that rejoices in the name of
5,5'-dibromo-4,4'-dichloroindigo. This particular
indigoid dye sticks strongly to the nearest
protein molecules and does not diffuse into fat or
other lipids, and does not form visible crystals.
This is one of the most thoroughly studied
reactions in enzyme histochemistry. If the method
was carried out correctly there should be no
"nonspecific" deposition of
5,5'-dibromo-4,4'-dichloroindigo more than 500nm
from a beta-galactosidase enzyme molecule.
There are some minor controversies about the
sensitivity and specificity of indigogenic methods
for lysosomal enzymes (with acidic pH optima), and
for many of these enzymes there are alternative
histochemical methods.
2. I'm assuming that you are using the indigogenic
X-gal method to detect the lac-Z reporter gene,
which encodes a bacterial beta-galactosidase that
works at pH 7+. This gene is tagged onto genes
that encode more interesting proteins in
experiments with altered cell lines, transgenic
mice etc. Cells that transcribe and translate an
added or modified gene also make the bacterial
enzyme encoded by the reporter gene. Histochemical
detection of a beta-galactosidase active at ph 7+
indicates that the "more interesting proteins" are
probably being made in the same cell.
The problem with lysosomal enzymes referred to
at the end of Part 1 (above) does not arise with
indigogenic detection of the lac-Z gene product
because the pH of the medium is significantly
higher than the pH optima of lysosomal
glycosidases.
"Normal" (animal) beta-galactosidase activity
would be detected only after an unduly prolonged
incubation. The false-positive result would also
show up in your negative control sections of
tissues known not to express the lac-Z gene.
If your known-negative controls show no
blue-green colour and your transgenics (or others)
show "excess nonspecific X-gal stain" there is no
"excess". You must be working with a tissue whose
cells are putting out lots of the bacterial
enzyme. The genetic engineer should thank you for
providing evidence that the introduced genes
entered the host organism and were successfully
transcribed and translated.
If you have no known-negative and
known-positive control results, ask your boss
for more detailed advice.
3. This is an answer to your beautifully concise
two-line question, cited below. The indigoid dye
is insoluble. It was probably deposited at the
site of the enzyme, if the histochemical method
was done by the book.

I too have found this to be true with bx sponges also. I work with
clinically engineered skin, which is much thinner than normal human
skin. The specimens had to be kept flat. The sponges created all kinds
issues. I ran across a product, called a bx capsule, which is a mesh
screen that folds shut(like the bx cassettes). The tissue is held
securely, and flat, and the carryover is decreased dramatically and
there is no artifact. You can order these from several vendors.

Fellow Histonetters,
We are a large reference lab that processes various medical facilities tissues. We have a new client that insists on using the small screened biopsy cassettes for every tissue type, including breast, uterus, parotid gland etc.
We have ordered the appropriate routine cassettes with the slots for their large tissue but they refuse to use them and the quality of the resulting samples is sub-optimal at best.
Our patholgoist has volunteered to speak to them since most of Histology's requests fall on deaf ears.
Are there any articles and/or opinions on this issue? I have been in the field for quite a few years and this is the first time I have encountered resistance like this. Most of the grossing is done by a PA who actually does a nice job with the actual grossing, it's just using this screened cassette that we are unable to change.
Thanks for any opinions here.

hi Marc,
pikro-aniline blue:
add 0,5g Anilinblue or methylenblue to 500ml saturated aquous solution of
picric acid.
everything else is done like van Gieson
Result: collagen, basement membranes and reticulin blue; cytoplasm yellow
John Kiernan´s book says reticulin and basement membranes are not stained if
you use indigocarmine (0,5 g in 200ml) collagen should be blue-green in this
case
greetings
Barbara

Methyl blue, NOT methylene blue! Methyl blue is
one of the components of aniline blue, which is
often a mixture of related anionic
triphenylmethane dyes. (Methylene blue is a
cationic thiazine dye with very different staining
capabilities.) The picro-aniline blue methods pick
up thin collagen fibres that are missed by van
Gieson. The staining pattern is closely similar to
picro-sirius red F3B, but aniline blue does not
enhance the birefringence of type 1 collagen.
