[Histonet] Meditech pathology module

[Rice, Michael]

Hi All,
We are currently being asked to convert from Copath to Meditech as our pathology module. Does anyone out there have experience with them. So far every thing  that I have seen shows it to be inferior to Copath as well as being extremely difficult to build as we in the department are responsible for that. Any and all opinions are welcomed.
Thanks
mike

Hi Eric, 
Have you considered asking your Ventana rep for information on their FITC reagents. The expiry dates on those are far longer than any you will get from making your own up. Approximately 12 months +

Hello Listers,
 
We currently do immunofluorescence for IgG, IgA, IgM, C3, C1q, Fib., Kappa, Lambda, and C4d on renal biopsies, and the first four on skin biopsies.  We are using Dako Antibody Diluting Buffer and mostly Dako FITC antisera.
 
We currently make up about 1 ml of each, and the dilutions last us between 1 and 3 weeks.  We would like to keep them longer if possible, making them up in larger quantities, possibly with the goal of transferring them to dispensers on our Ventana XT's.
]
Is there anyone doing the same immunofluorescence panel and dilutions, and if so, how long are you able to use your dilutions once made?
 
Thanks for your assistance,
 
Eric Gagnon MLT

I have a problem with bone marrow aspirate controls. The problem is that we are limited to the amount of controls we can collect.  Even though the tissue control is working if the aspirate control (which are difficult to obtain) does not work we are being asked to repeat the stain until we find a aspirate control that is acceptable. Since I can not guarantee the aspirate control contains an adequate amount of Fe, I will be wasting time and reagents. 
Can anyone give feedback on how they process stains on bone marrow's, do you only use a tissue control, does anyone know where bone marrow aspirate controls -positive for Iron -can be purchased commercially?

What antibodies are people using to stain for cytokeratins in mouse

   Cynthia,

   We  were  not that successful either with the Dako rabbit CD3 antibody
   on  mouse  tissue.  We  changed to the LabVision CD3 rabbit monoclonal
   (clone  SP7) and this worked very well on human, rat and mouse tissues
   (both  cryo  and  FFPE).  E.g.  for staining FFPE: HIER with Tris-EDTA
   pH9.0,  CD3 1:1000 (60 min, RT), polymer anti-rabbit/HRP (30 min, RT),
   DAB+ (5 min, RT).

   Hope this helps,

   I have been using Dako CD-3 on murine formalin fixed paraffin embedded
   tissue and am experiencing some variation in staining. My protocol:
   pretreatment  with  Citrate pH 6.0 @120C for 5 minutes under pressure,
   an
   overnight incubation of the primary 1:1500 @4C, followed by 30 minute
   incubation with Vector biotinylated anti Rabbit IgG 1:250, 30 minutes

   Ventana Nexus @RT using their AEC. I used to do the stain reliably but
   have  a  new  lot and reliability is not optimal. I use a mouse spleen
   and
   brain  with T-cell infiltration as positive controls and a NL brain as
   a
   negative  control.  Sometimes the stain is so crisp and other times it
   is
   muddy with a decrease in the number of cells st! ained. I

   Dear Scott,

   You  didn't  tell us what detection system was used. Your story sounds
   reminds   me   to   our   first  experiments  with  streptavidin-based
   detection on   mouse   spleen  when  we  were  confronted  with  heavy
   endogenous   biotin!   For   staining  mouse  spleen,  either  avoid a
   streptavidin-based detection   system   or   try  to  block endogenous
   biotin as Gayle suggested.

   Please  realize that if the above is true and/or Gayle's is right with
   her  suggestion  concerning  the  adsorption  of the anti-rat reagent,
   the signal  you observe is no autofluorescence but "unwanted" specific
   fluorescence!

   Dear Dr. Sohail,

   You  didn't  write  us  what detection system was used for this double
   staining.  The  fact  you observed overlap of SMA and vWF (which isn't
   very  likely  indeed) makes your detection system a bit suspect. To my
   opinion  the most straightforward (and safe) ways to doublestain these
   antibodies are:

   A:  cocktail  of  SMA  (mouse) + vWF (rabbit), followed by a secondary
   cocktail composed of goat anti-mouse/FLUO-1 + goat anti-rabbit/FLUO-2

   B: cocktail of SMA, clone 1A4 (mouse IgG2a) + vWF , clone F8/86 (mouse
   IgG1),  followed  by a secondary  cocktail composed of goat anti-mouse
   IgG2a/FLUO-1 + goat anti-mouse IgG1/FLUO-2

   Lots of success!

      While doing double staining I have encountered overlapping of  both

Hello again. Sorry for a bit unclearly formatted question.

More specifically, I'm doing samples of bovine blood vessels, obtained 
from a slaughterhouse. So perfusion is unfortunately out of question :)
And this is about REALLY big vessels, such as the bovine aorta. So the 
samples are bits (about 1 cm2) of vessel wall cut off and placed in PFA 
for overnight at +4C, then processed for paraffin sections in a routine 
manner.

And yes, this is primarily about blood vessels, not lymphatics.

Regards,
Mikael

We run a one-step FNAC breast clinic and have been using Diff-Quick as our
stain; I personally don't like it as I prefer Paps but there you are. We had
a recent FNAC that showed histiocytes in the tail of the prep but little
else. As you know the bubbly cells tend to migrate to the edges as they are
lighter but what we initially failed to notice was that in amongst the blood
were poorly stained clumps of cells. After restain with a 'proper'
Romanovsky stain they magically appeared and were benign. I shudder to think
what would have happened if they had not been spotted and had been
malignant. The problem I guess was the blood and together with the slow
drying of the smear.

Diff-Quick is fast but can have this effect, does anyone have a technique
that is nearly as fast as Diff Quick but more robust in these cases?
