Fernando,
My answer to this is it depends, I don't believe there
really is a universal "best".  I have worked in
clinical, industrial and currently in academia, I
handle human and animal tissue/cells and do a large
variety of IHC/IF/ISH/FISH work.  I will tell you now
that primary incubation times are never written in
stone because they are only ONE part of the procedure.
 Each lab has to work out its own conditions based on
the variables they have to work with.  Both the
conditions and variables differ from lab to lab.

In my lab currently we run PCNA, bcl-2, Cyclin D1,
GSTpi, 3-clones of p53, and BrdU at one to two hours
incubation at RT.
All NFkB subunits, 8oxodG, BPDE, Cox 1 & 2, p21,
3-nitrotyrosine and MGMT overnight at 4 C.

Just name a few.
