[Histonet] cd34, cd117 (ckit) and dog-1

[Vet Patoloji via Histonet]

Hello histonetters,

I'm looking for some antibodies that are working on feline (cat) tissues
for ihc.
I would be very happy if you could help me with this.

Best regards.

Thank you all very much for your suggestions. I'm going to play around with a 
progressive H when I return from vacation next month. I do have safranin on 
hand but will need to order some phloxine to experiment with. I will probably 
need to order some additional supplies to make the hematoxylin. I'm not sure 
yet if I'll start with Mayer's or Gill's or maybe even Erlich's.

I should note that cutting at 2 isn't required, but it is desired once they saw 
that I can. And since I can, I aim to please! :-)

In addition, I'm looking forward to trying the oven dry method before 
coverslipping. A rapid dehydration isn't really possible since I'm working with 
a xylene substitute (Pro-Par) and have been battling eosin carryover but that 
is a whole different animal for another thread.

Thanks again! I'll report back in a month or 2.

Re: [Histonet] CD34 for primate tissue

[Croix, Denise via Histonet]

Hi Cathy,

When I was doing work with NHP tissue (both flow cytometry and IHC) there
were several sources that I utilized for info on antibodies that were
cross-reactivity with various NHP species.  The NIH hosts a NHP reagent
resource website (nhpreagents.org) that shows which commercially available
antibodies cross react with non-human primate tissues.  They note that
there are discrepancies reported about cross-reactivity with the QBEND10
antibody for  rhesus and possibly cynos.  You will need to still check with
the vendors to confirm if the antibody has been tested in FFPE specimens as
that is not indicated on the site but it should give you a starting point
to work from.

I've had personal experience with cyno & rhesus T cells where individual
monkeys would not react with certain anti-human antibodies.  For example, I
had a couple of research animals that were negative for a CD3 antibody but
yet they stained with CD4 and CD8 antibodies.

Good luck!

Denise

Re: [Histonet] CD34 for primate tissue

[Elizabeth Chlipala via Histonet]

Cathy

Before doing that I would check the sequence homology of the immunogen between 
human and rhesus.  I would do this for all sources of the antibody, if the 
company does not want to provide you with the sequence then technical support 
should be able to blast the sequence for you and get back to you the sequence 
homology, greater than 70% is worth a shot it may not work or it may not.  You 
also need to check if it's the same clone it might be the same antibody just 
distributed by different vendors, check the protein concentration, purification 
method, isotype, and if there are matching images you are likely looking at the 
same antibody so you don't want to waste your time with ordering the same 
antibody but from a different vendor.Remember information on specification 
sheets can be inaccurate - this depends upon the vendor, some vendors actually 
test internally while other vendors rely of user for cross reactivity 
information so you need to take that information with a grain of salt.
   My suggestion is to take a look at the antibody on CiteAb - this website is 
a bit better than biocompare since it rates antibodies by number of citations, 
check to see if the other antibodies have publications with your use case.  The 
link for CiteAb is https://www.citeab.com/ We find with some antibodies that 
work across species that the primary antibody concentration may fluctuate so a 
concentration that works in human may not work in the particular species you 
are working with.  There are many other parameters such as time in fixation 
between your human tissue and rhesus tissue.  Are you getting any hint of 
staining or is it just completely negative.

It's really important to spend some significant time upfront when researching 
antibodies for a new target - you want to biases yourself towards success.  If 
you are an NSH member I posted a worksheet for target development on the BLOCK 
you can access it there.

Rhesus is a species of old world monkey.  There are a couple of other companies 
that have this same clone and on their datasheets they say it cross reacts with 
rhesus monkey.  The CD34s (2) that I have do not state on their data sheets

the companies that say it does.  I guess I will just break down and purchase a 
different clone that states it works in rhesus monkey.

Re: [Histonet] CD34 for primate tissue

[Eddie Martin via Histonet]

Hi Cathy,

I haven't heard of the cross reactivity with monkey species using Novocastra 
CD34. However, novocastra's antibody is a monoclonal antibody. You may get 
better staining utilizing a polyclonal CD34 instead. Thermo-Fisher and Abcam 
provide a polyclonal CD34. If you reach out to them, they may be able to 
provide you with a sample size 0.1 microliter if they have them available. 

I hope his helps!

Best,
Eddie

I am using rhesus kidney as a control (getting no signal), but I also ran some

[Histonet] CD34 positive control

[Joel Reichensperger]

 I have a doctor who wants to stain some tissue with cd34. I need to 
know if anyone can recommend a good positive control tissue for this 
antibody. The staining will be done in paraffin embedded sections. 
Thanks in advance.

[McMahon, Loralee A]

Just about any tissue should work.   It stains for Hematopoietic 
stem/progenitor cells, bone marrow stromal cells, endothelial cells, embryonic 
fibroblasts 
We use a sausage style control here with about 30 different types of tissue.

[Histonet] CD34 Control

[Silverman, Jeffrey]

Joel,
A section of skin will be a fine CD34 control. All collagenous connective 
tissue, including the dermis,  are rich in CD34+ dendritic interstitial 
fibroblasts as well as CD34 positive endothelium in the resident vessels. 
Actually, in my lab we use a section of fallopian tube from tubal ligation, 
they are loaded with the fibroblasts and vessels.

[Histonet] CD34 and CD41 in paraffin sections

[neil . macintyre]

Hi everyone

Has anyone any knowledge on the use of  CD34 and CD41 in formalin fixed 
paraffin embedded canine 
tissue? It's for a suspected case of Acute Megakaryoblastic leukaemia and the 
identification of 
immature megakaryocytes.

Many thanks

Neil MacIntyre
