[Histonet] Freezing human skin biopsies for cytokine ICC

From:"Downs, Heather M."

We often section human skin punch biopsy, using a sliding microtome and dry ice.
We fix our tissue for 12 hours in PLP, followed by a wash in Sorenson's and
placed in croprotectant for 24 hours before either cutting it, or freezing @-20.
We do a free floating immunostain and cut at 50 microns with no problems.

It depends upon your SOP's most calibrated thermometers have a little
statement at the bottom of the certification that states that most
institutions recalibrate once a year but you must follows your own SOP's.
You then need to take into consideration what guidelines you are following
and what the standards are.  What I'm saying is that you can write in your
SOP's that you are going to calibrate once every 5 years, but when you get
inspected will the inspector think that is good enough. The kicker is the
cost to recalibrate is more than a new thermometer, we just purchase a new
calibrated thermometer each year and that's what is in our SOP's.

Patrick,
I remember reading in one of the early immunohistochemistry texts that 
the reaction between a primary antibody and its epitope was believed to 
require 96 hrs. at 4 deg. C to reach equilibration.  Whether or not 
that's true for your antibodies, it is the kind of precedent that 
underlies the procedures typically used today.
The other issue is penetration--if you need tissue to be evenly labeled 
throughout the depth of the specimen then section thickness and 
embedding material may require long incubations (at least).  If surface 
labeling of an abundant epitope is enough to tell you what you want to 
know, a good primary may require less than half an hour!
Happy histo,

I just received the catalog yesterday and was thrilled to see this product.
Although a bit pricey-$1530, we should be able to capture the cost with
reagent and materials savings, as well as tech time.

Thanks to all of you who responded to my inquiry,

Annette

Helen,
  I just saw a new "TMA Builder" that Lab Vision has available cat# TMA-001
under Research Tools in their new catalog.  It looks similar to what
woorie-medic's tissue punch extractor looked like.  The mold is totally
different though, it has a metal clamp & a metal recipient base mold with 24
core indentations.  Have you seen it?  Any comments?

Can anyone recommend a good system for making tissue microarrays. We
are not
a large volume lab (approx 250 IHC per month), so I would be looking
at
manual methods for accomplishing this. My planned uses would be for
new
antibody evaluations and controls.

Thanks, Annette

Hello histonetters,
                                       I hope someone can help me with a 
question about how to freeze a human skin biopsy. I am in research but am=20
in collaboration with a clinical lab that will be collecting human  skin 
biopsies for me to do cytokine ICC  of TNF,IFN-g, among others and 
possibly cell makers. 
       My question is how do I instruct them in freezing the skin so that=20
I get the best sample for this staining. I am going to embed the sample 
once it is in my lab for cryosectioning.  Also if people know of 
manufactures of antibodies that sell  TNF,IFN-g that work in human tissue=20
that would also be helpful, I have found a few but many different 
protocols and fixations.

Any thoughts how be helpful.

Jamie

Content-Type: text/plain; charset=ISO-8859-1; format=flowed

hello, one of our collaborating researchers has me searching for 
gelatinized slides to be used for Golgi staining for cryosectioning  100 
micron mouse
spines.  It appears that she came up with this idea after reading about 
a similar protocol on brain. I have searched the histonet archives and 
the only thing that I can come up with is info on gelatin subbed slides. 
Thus far I've only found one company that has commercial gelatinized 
slides. Please pardon my ignorance but is there a significant difference 
between the two whereas one is preferable for certain protocols for 
which the other is not? And if any of you are currently using commercial 
gelatinized slides will you provide me with contact info on your source? 
Thanks, Atoska

Initially I found to get new thermometer each year was easier and economical,
but after some research I came up with a cheaper solution. Now  in our lab we
recalibrate NIST calibrated thermometer every year. We keep two sets of
thermometers for each freezer and fridge and recalibrate and use them alternate
year.One which is currently in use is just got calibrated in January,07and will
expire in January,08. The other one which is expiring  in Feb ,07 we will send
for recalibration in December ,07 which will come back by January,08 and we will
use recalibrated one for the next year. We send our thermometer.to the following
company. .   Calibration Services
  Control Company
  4455 Rex Road 
  Friendswood, TX 77546
   
  They charge $15 for each thermometer and $8 for shipping. We get two
thermometer done in $50 including shipping from both ways. I found it cheaper
that way then buying new thermometer each year. I believe that calibration can
be done in house too. I am sure  there are very  smart people out there in this
field who may have better ways to deal with this issue.
