I would beg to differ with Rene on this one. I don't believe antigen
retrieval is "by definition" using heat and sometimes pressure. I would
define antigen retrieval as any process that restores the original three
dimensional structure to a molecule altered by fixation (typically formalin
fixation) such that it can be recognized by the detecting antibody.
I have performed antigen retrieval by leaving slides overnight in the
refrigerator immersed in PBS + 0.05% Tween 20. I'm sure there are many other
ways to accomplish antigen retrieval, heat merely accelerates the process.

You can always "open" the antigenic sites with enzymatic digestions. The
antigen retrieval is, by definition, using heat, and sometimes additional
pressure to have an even higher heat level.

Does anyone out there have any methods of antigen retreival not using heat?
