[Histonet] CD4 and CD8 in human FFPE

Wed Jan 11 01:38:03 CST 2006

Dear Histonetters,
I've got many requests asking for our protocol for staining CD4 and  CD8, - therefore 
I think it is best to answer in general on the histonet for all users. Since I was out-
house for several days, I apologize for any delay in my answer !

We make pretreatment for CD8 and CD4 in a household microwave oven, place the 
slides well submerged in buffer (0,8 liter container) for 30 minutes, using 800 Watt.
For bone-marrow (decalified by EDTA in a ultrasonic bath), we use as buffer 
monocitrate pH 6.0.
For all regular human tissues, we use monocitric buffer pH 7.2

For CD4, we use Zymed "ready-to-use" monoclonal antibody 08-0101.
For CD8, we use Dako antibody (M7103) in a dilution 1:40

For both markers, detection is done with the Zymed detection kit "Zytochem plus 
HRP 5000".
All stainings are done in daily routine on a Lab-Vision Autostainer. Sorry, but we have 
only experience in human FFPE tissue. I have no idea if it works in bovine tissue as 
well. In mouse tissue, it doesn't work - that's why I posted my initial request to 
histonet to get protocols for mouse FFPE. All the answers I got hint to the fact that 
there are no reliable protocols or antibodies for CD4/8 in mouse FFPE so far. 
However, we will not give up and try harder to solve this dilemma - as soon as we 
have answers, I'll let you know !

Best regards - and thanks for the many answers and comments from you.
Have a successful new years 2006, - with less war on earth and more thruth.

Sincerely yours
Reinhard.

Hi Patsy,
we do a lot of CD4 and CD8 in human FFPE tissues, even in BM after decalification. 
It works very good and is daily routine in our lab. If you need advice, give me a mail.
We now got some hints how both markers could work in mouse tissue, too. If we 
succeed, we'll let you know.

best regards
Reinhard.

Reinhard,
Could I please have a copy of your protocol, we have had lots of trouble 
trying to stain with
CD4 and CD8 in bovine tissues.
Any advice you can give would be most welcome, particularly about antigen 
retrieval.

      Hope everyone has a happy Christmas,
             Regards,
                         Laurie.
