Have you tried any other clones? Can you get hold of some (free / cheap /
small) samples? I have found that our Ventana Benchmark doesn't like the
occasional clone, ie 1D5 (Ors), and certain clones for CD138 and calretinin.

Hello Everyone,

We are a small Veterinary Pathology laboratory and our Pathologist would
like to look into a Microwave Tissue Processor.  He would like to know the
pros and cons of such a processor.  We would only need a 30 specimen
processor.  How long do the tissues need to fix in formalin before using the
microwave?  Does the specimen need to be fresh or can it be 3 days up to 2
weeks old possibly autolyzed?  Does the processor use more alcohols?  We
would appreciate any feedback from techs that have had experience with using
the microwave processors.  Thank you in advance.

Steve,

I've worked in several low-temp "bio"- type labs, and they all used Fluke
digital thermometers.  

You can match the thermocouple to the temperature range you need to measure.

The website can steer you to a dealer or someone for tech questions, but I
know the J- and K-type thermocouples can read temps down near -200 degrees
C.  
That's around the temp of liquid nitrogen (-196) so it should do you well.

Go to Fluke's homepage here.  Then follow the links:
Products -> thermometers -> Fluke 50 Series II Thermometers ->
Specifications

Cheers,

Bob

Dear Steve, I presume you are freezing muscle biopsies, or possibly research
material.
This isopentane/liquid nitrogen method is more an art than a science. 
Altitude of your lab and humidity of your ambient air, are the 2 major
limiting factors.  The most important thing in the freezing is not measuring
the temperature but rather visual assessment of the state of the isopentane.
We put the isopentane in a 250 ml stainless steel beaker and lower it slowly
into the liquid nitrogen.  We wait to freeze, until the isopentane has
formed ice all around the walls of the beaker and all the way up the wall of
the beaker, and completely across the bottom of the beaker.  It will be
syrupy.  We use 25 seconds of freezing (I know the books say 5-10 seconds).
Our lab is at sea level.  It is also often humid here.  We discard the
isopentane every 3 months when there is no major humidity and more often
(every 6 weeks) when we have a run of humid weather, or when we have a
problem with freezing artifact, or when I think my assistant has been sloppy
with its storage.
We keep the beaker very clean i.e. we scour with steel wool.  We make sure
there is no residual water in the beaker (I keep 2 beakers so one is freshly
clean and dry at all times).
I have not used the thermometer since I was a young attending a long time
ago!!!
Best
Karen

I've done this both ways, with and without.  I once thought that the
cassettes had to be held in molten paraffin to ensure a homogenous block - 

I've since changed my mind. It doesn't matter.  I prefer a hot dry holding
chamber - less messy.

I've done this both with and without melted paraffin.  I prefer having a dry
holding tank.  Less mess.  Less waste of paraffin also.   As long as the
holding tank keeps the cassettes from solidifying I think they can sit for
quite awhile.  Or at least as long as it take to embed a tank full.

You discard your isopentane every 3 months? Is this stuff you've been 
using for freezing, and you keep using the same isopentane? And it 
stays cold the whole time?
I hope not.
The cold isopentane is getting enriched in oxygen as it's being used, 
and this heightens the fire hazard.
Why not freeze into (all right, everyone who's read my rants before 
can ignore me now) slush nitrogen? Colder, faster freezing, better 
freezing, and no flammable/explosive liquids or gases involved.

To restore basophilic properties to tissues as the result of overexposure to
decalcifying solution:

 

Method 1

1.    Deparaffinize and hydrate slides

2.    Place slides in 5% aqueous sodium bicarbonate solution from 4 hours to
overnight

3.    Wash in tap water for 5 minutes

4.    Stain as desired

 

Method 2

In step 2, use 5% aqueous solution of ammonium sulfide overnight

 

Method 3

In step 2, use 5% aqueous solution of periodic acid overnight

 

Hopefully one of these methods will work for you.

We do not add paraffin to our holding chamber.   But they do not sit
there very long, as we start embedding right away.   Is there a reason
you want them to sit for a time before embedding?

If it's going to be a really long time (or even to hold extra tissue,
unembedded for a great length of time) just pull the cassettes out and then
put them back in to heat up right before embedding.

We do not add paraffin to our holding chamber.   But they do not sit
there very long, as we start embedding right away.   Is there a reason
you want them to sit for a time before embedding?

All thoughts, opinions, experience is appreciated...Thanks.

Hello Histonetters,
We would like to see if anyone can help us with an antibody optimisation for
Bcl10?
We have the Zymed Bcl 10 ,clone 151.
We have tried HIER using citrate ph 6.0,citrate EDTA ph 8.0,and Dako TUR
both on the Ventana and the Bond Max.Our dilution ranges have been from a 1
in 50 up to 1 in 2000.
Our slides look "muddy" with distorted morphology.With no specific
staining.We are using a reactive tonsil as our control.
If anyone is familiar using this and can offer us some help we would really
appreciate it.
Thank you very much

Does anyone out there do ALK 1 on the Ventana Benchmark? If so, I would be
grateful if you could let me know what clone you use, what the protocol and
dilution are, and if you could spare me a positive control block. 
I have tried 2 clones - Dako's ALK 1 and Lab Vision's SP8 but to no avail; I
have had experience of certain clones of some antisera (Vector's CD 138 and
Dako's calretinin for example) not working on the Benchmark and it's
possible that these clones are not suitable. Having said that, we only had 2
cases and possibly they may have been negative for ALK 1 anyway. I used the
lowest recommended dilution, both the mild and standard heat protocols, and
the 3 primary incubation temperatures (room, 37 and 42) and even tried
protease and no retrieval but got nowhere. I have also tried to get a known
positive control block but no one I've tried has one!
All assistance appreciated!

I do not put any extra paraffin into the holding chamber. If I am not
going to embed right away I take the cassettes out of the processor and
let them cool off with the paraffin hardening around it. I have not had
any complaints with tissue handled in this way.

Hi All,
 I was wondering if you guys can help me answer the following questions
about archiving histology samples.
Our Histology Lab archive the samples(including wet samples stored in 10%
formalin, blocks both paraffin and plastics)  indefinitely and since we are
running out of space it is becoming a great deal of problem. 
 
The following are my questions:

*	How long do you keep the samples stored in 10% formalin? 

*	How long do you store the blocks (paraffin and plastics) in
research? 

*	Is there any agencies like the FDA, CDC or CLIA outlining this task?

thanks,
Nena

My co-worker just successfully ran a predilute polyclonal ALK from
BioCare Medical on our Benchmark with an MCC1, 32"ttn and no  block.  We
had previously only run it on the Nexes and haven't run it on our XT
yet.  
Unfortunately, we are not flush w/ control tissue (we only have 1
positive case from 1999) so I can't send you a block.  However, would a
few cut slides help you get started?
I know that when I first worked up this antibody I didn't have much luck
w/ the rabbit monoclonals I tried.

Hi Everyone, sorry for the delay in responding, my
histonet digest was "lost in space" for a few days. 
We don't do ADG here, but I also use the Dysferlin
antibody from Novacastra (purchased from vector) with
regular IHC (no FITC) for frozen sections. I use Clone
Ham1/7B6(new vector number VP-D503).  
  Air dry frozen sections (usually 20 min or more). 
Dilution:  1:20 at rm temp 1 hr.
 I use with Vector R.T.U. vectastain kit (use
secondary 30 min <@t> 37degrees C. ABC reagent 1hr. rm
temp.  I use DAB from Vector for 15 min.  I usually do
a very pale counterstain or none at all depending on
pathologist.
I hope this is of some help to you.
Have a good weekend,

Sarah,
I use  Dysferlin from Novocastra on frozen sections,
but not FITC, just
regular IHC. If you're desperate we can talk.
I use it with a detection kit for mouse, any vendor
will usually do and
DAB as the chromogen. No special scope is needed.

Hello histoneters,
 
    I could really use any procedural information
anyone has on
Alpha-dystroglycan (antibody only available thru
Upstate) and Dysferlin
(antibody from VectorLabs).
 
        I have been attempting the stains for 2months
now with no
satisfying results. I have tried several different
procedures/fixatives/incubation times/dilutions/. I
perform a battery 
of
14 neuromuscular Immunoflourescence, they are all
BEAUTIFUL fitc green
with no background staining (picture perfect)
.....except these two
boogers. PLEASE HELP me make my pathologist proud!!!
