Re: H&E Staining

We do not have a high volume of rat tissues and thus stain by hand. Generally we have increased the time in hematoxylin and eosin slightly because the tissue is so dense, even if cut at the same thickness as mouse tissue. We do long term storage in 70% EtOH and have not had any problems with staining after that.

Hope this may help

Jennifer

Hello,
I am looking for a renin antibody for IHC on FFPE rodent tissue. I searched around and couldn't?decide which one I should try.?Could anybody recommend one?
?
Thanks in advance.

Hello Histoland,
Wondering how many of you use specimen tracking systems (bar-coded) and what type of system you use.
Pros-cons of each system?
Thanks,
Stacy

Histonetters,
    I am looking for some help in getting IHC slides out in an 8 hour period of time.  Here is some information.

*         We have a busy Immunohistochemistry lab  and the volume of requests keep increasing.  We offer approximately 150 different  IHC stains ( including ISH and Dual ISH for Her 2).  Generally, there are request for  >150- 200  IHC tests twice a day, not including negative and positive (same slide) controls.

*         The techs pull an AM log at 6am and another at 1pm.  The 1pm log will be handled while waiting for the IHC's to be completed from the 6am run  and these will always be run overnight.

*         The 6am log requires that one tech start cutting each block for multiple IHC stains.  (A search for blocks and the necessary control slide occurs by the same person).   The slides are kept in a 60 degree oven for about 60 minutes.  Most of these slides will be ready by 2-3:30pm.
   Here is my question.  If we allowed requests for IHC stains to wait until  9AM  how could we still get slides out by 3:30pm-4pm? In other words we would not have access to an LIS log until 9am so that the pathologists could order from the morning biopsies.  What is the best way to do this  with 3 Ventana Ultra's  and one Benchmark XT.     The blocks ( usually 40-50) need to be cut; sit in an oven and then get labeled and placed on the Ventana's.   All longer stains such as ISH would be run overnight.
                                   The following  tasks makes the 3:30- 4pm deadline difficult:

*         Searching for the blocks

*         Cutting the blocks (40-50) onto control slides + negative control

*         One hour in the oven to dry  (Can we use 30minutes?)

*         Attaching labels to 150 slides and setting up instruments

*         One microtome

*         2 techs/ some of the time
     Can you share your workflow with me if you do a similar volume of slides within an 8 hours period.  How would you staff the two IHC techs to gain the most efficiency.  As you know the fuller the instrument the longer the staining process.

   Thank you,

Dear Pat,
here some inputs. If usefull, you have to decide for yourself.

Ad controls: We use for most of our antibodies an "universal-control". This is put together with tiny pieces of normal tonsil, appendix, skin, liver and pancreas. If you are interested, look at the website of NordiQC.
Some labs prefer to cut the controls in advance. This can also save time, but the controls shouldn't get older than a week.
Ad speed: we cut the urgent cases in advance besides the HE with 6 slides per block. These are needle biopsies from breast, liver, kidney, .... etc.; the pathologists only have to order a panel.
Ad drying: we often skip the drying in the oven at all. But it is important to get rid of the water under the sections. (Besides: drying at high temp for longer period can alter stainability.) Ad LIS: we also have no LIS, but a light-version of it. We use a WORD-document as form. The pathologists can mark the wished antibodies and print the sheet directly onto our printer in the lab.
Ad organisation: isn't it possible with 4 instruments to keep the same antibodies on each instrument? For example: one machine is the breast-machine, one for lymphomas, etc. If this is possible, you can add a "machine-code" on the labels and only look at this code while filling the machines.

We work only with one Ultra. First technician comes at 6.30 and starts the first run until 7.00-7.30. Second run is started at 10.30-11.00 and the run over night is started around 15.00. The most slides have to been cut at afternoon. And if there are more than 30, they go into the morning run.
This gives for the urgent biopsies an IHC-TAT about 5-6 hours (from HE delivering to IHC delivering). Most other cases are ready over night (HE delivering till 12.30 and IHC-ordering-deadline at 14.30).

Hope this helps

Pat,

Right off the bat I can see 2 things that could speed things up for you.  We have Ultras and only dry our slides for 10 minutes at 60 d C.  If tissues don't stay on well, try some "Stay On" in your water bath; we're experimenting with that now.  Also, we spend way too much time ourselves searching for blocks.   See if there is a way to have them organized immediately after sectioning the H&Es so they are quicker to find...we are struggling with this.

My 2 cents; good luck.

Histonetters -

We had some rat tissues that were removed at necropsy and immediately fixed in formalin for 48 hrs.  Since the tissues could not be processed after the 48 hr fixation they were transferred to 70% ETOH for about a week, then processed and stained with H&E.


The H&E staining looks faded/washed out when compared to previous rat tissue that was fixed for 48 hr and then processed and stained without the extended time in 70% ETOH. The reason for limiting the fixation to 48 hr in the more recent study was that we were doing some IHC stains and wanted to keep the same fixation time as the previous study.

I have extra unstained slides left over - any suggestions on how to get some better, crisper H&E results?  Has anyone observed the washed out H&E appearance from tissues stored in 70% ETOH.

Thanks,
Brett

I forgot to mention that the H&E was performed in another lab at our facility...most likely on an autostainer.  We just did the IHC studies and I have always used 70% ETOH for tissue storage ... never heard of this staining phenomenon happening before.

I am interested in the answer as I use this same technique on my rodent samples and have not had this issue.

Hi Brett,

That the H&E staining looks faded after storage in 70% seems very unlikely. We do this with rat and mouse tissues all the time. Did the other lab use a different Hematoxylin, Eosin, or used a different staining protocol on the autostainer?

Subject: [Histonet] H&E staining question

Histonetters -

We had some rat tissues that were removed at necropsy and immediately fixed in formalin for 48 hrs.  Since the tissues could not be processed after the 48 hr fixation they were transferred to 70% ETOH for about a week, then processed and stained with H&E.



The H&E staining looks faded/washed out when compared to previous rat tissue that was fixed for 48 hr and then processed and stained without the extended time in 70% ETOH. The reason for limiting the fixation to 48 hr in the more recent study was that we were doing some IHC stains and wanted to keep the same fixation time as the previous study.

I have extra unstained slides left over - any suggestions on how to get some better, crisper H&E results?  Has anyone observed the washed out H&E appearance from tissues stored in 70% ETOH.

Thanks,
Brett

Hello All!

Can someone recommend a company that does DAB waste testing? I would like to
get our waste tested from our Ventana Ultra. Thanks.
