Hi Inan,
2h post-fixation for immunohistochemistry on mouse brain is usually more
than enough. We use 1h post-fixation at room temp for mouse brain
following storage (sometimes, for many weeks) at +4 C in PBS before
sucrose cryo-protection, embedding and sectioning.

Merced is correct about longer fixation inducing more cross-linking,
possibly making immunostaining more difficult.
Much depends on the antigen you are looking for.
I disagree that the tissue will become brittle, this is not my experience.

The longer the tissue sits in paraformaldehyde the more the proteins in the
tissues will become cross-linked due to multiple methylene bridge
formations and could require very rigorous antigen retrieval or may even be
beyond retrieval; the tissues could become brittle as well due to
over-fixati
