Thanks to all who replied to my question.
It is not our usual procedure to leave slides overnight in buffer after
AR and not one that we will ever repeat.

Brett, how long? I've left them overnight before proceeding without any
problems.
It would not be re-fixation as with formalin. However, if it is in a
detergent buffer it might cause some other kind of denaturation.

If we need to hold retrieved slides for awhile we hold them in water up to 4
hours. Holding in water overnight leads to no signal. We have also tried
holding the slides in our Tris buffer and have found decreased or no staining.

hold in PBS as long as several days without any problem, under 4 C.

Perhaps reversal is not the right word...slides were left overnight in
buffer w/ tween. We got very minimal faint staining compared to previous
runs done in one day.

Perhaps the antigen is soluble and diffused out of the
tissue into the buffer?
