Re: mouse lung CD3 immunostain


I haven't used CD3 on mouse lung, but I have found that the ARK kit from DAKO works wonders with mouse monoclonals and mouse tissue.
It's extremely efficient, and I wish I could use it for all my other antibodies, i.e., rat, etc. The stain takes about 1 hour start to finish, and is sharp and crisp.
No need to use only DAKO antibodies, either.

Hello everyone

I am developing a method for staining formalin-fixed,
paraffin-embedded mouse lungs with an antibody to CD3.
After an initial review of the archives I was hoping
for some feedback with the following:

1. ANTIBODY - Dako, Serotec, Novocastra, other(?).
I'm sure they all work to some degree, but what are
some of the negative aspects?

2. CITRATE BUFFER - should I be concerned about the
length of microwaving time given that lungs are more
fragile than most other tissues?

3.DAKO ARK - does anyone have any experience with this
"time saving" kit that they could provide some pros
and cons?  For me, time isn't a factor if the results
are poor.

I look forward to your useful insights.  If anyone
knows of a method that they can point me to as a place
to start, I would be very grateful.
