Yes, I am planning on doing immunofluorescence staining and would like
to adapt a protocol to the autostainer, which has the built in washing
fluid.
I previously did fluorescence staining on the bench, and I know I always
used triton-x for permeabilization. I'm now just wondering if I begin
with
trying the commercial antibody diluent (in keeping with the general
practice of the lab), is the surfactant already in the solution enough
for
permeabilization or would I need added triton-x? And if I would need to
add more, why is this not necessary with immunohistochemical staining?
Thanks again,

Question: are you planning to do immunofluorescent staining even though
you
are now doing only enzyme immunohistochemistry with these reagents?
The size of the fluorophore molecules is not a factor but there are some
other considerations when doing IF.

Hello,
In my previous position, I prepared all my own antibody solutions for
fluorescent staining myself with varying levels of blocking serum and
triton-x for
permeabilization.
I'm now working in a lab that uses commercial antibody diluents and an
autostainer with its
own washing solution. Both the diluent and wash solution contain
surfactant, but the concentration is
not listed. I'm just wondering if anyone knows if the amount is
sufficient
for permeabilization in
fluorescent staining. So far in the lab we have only really been doing
IHC
and they have never added triton-x to
their solutions. Also, out of general curiosity, is there a reason for
needing more permeabilization in IF
compared to IHC staining? Is it because of the size of fluorophore
molecules? Any ideas would be much
appreciated.
Thank you,
