Yes,
I would also agree that this would probably be the case.
I have not tried to redo the DAB step after counterstaining,
dehydrating, clearing and mounting.
I would expect it not to work.
Though I could easily be corrected.

The new Ventana Ultra allows slides requiring titration/manual application of

because it is a continuous access system, any slide/any time. This is an

Our lab has, in fact, been "LEANED". We were somewhat limited by budget of

process of maintaining our processes.

Would anyone have a manual for the above embedding center? Or could tell us how

True, but unless you have every slide on the run as titration the machine
wont start. That's a good trick if you just have a titration run.

Yes, you can always run in "manual" modeediting the protocol to
"titration" rather than "antibody". That does indeed allow you to
manually apply the antibody when the instrument signals its time to do
so.

Liz, When I do some smaller odd type bone samples, in paraffin, we have found
the cutting pulls the cells out of the nice, lacunae network and the cells sit
on top. It is an artifact we have noted for years. Calcified sectioning might
be better. Vicki

Liz,
If your controls are fine but your bone marrows are not, could it be
the decalcification process that is damaging these antigens? Try using
EDTA for decal instead of formic acid.
Just a thought.

We have found that when using the Bond, it is easier to get started with 10
slides, or 1 or 2 small cases. Our pathologists make requests throughout the
day, and to have to hold up the entire run so that another case can be added
creates a delay in results.

You don't need to decolorize. Remove the coverslip, rehydrate to water (the
eosin will come out in the alcohol), and then begin your IHC procedure.
Hopefully, the tissue is mounted on an adhesive or charged slide. If not, you
may have to cut back your antigen retrieval. Also, you may want to
