Well, indeed I think we can't get immortality. Depending on the space we are 
in, we can live as long as itself, may be 10^37 or something as 10^100 years. 
I understand there is an enormous difference between these two values, but 
even the smallest is incredibly long when put against the current age of the 
space we see.

On the anti matter side:  I don't think matter would be anihilated by anti 
matter, simply over such long periods any proton and neutrons would 
disintegrate into neutrinos and positons, The anti matter destruction would 
take place between these positons and the electrons. Neutrinos would be 
shifted down in energy by space expansion, if they have no rest mass they 
would be cancelled by that process, if they have a rest mass, all would 
remains of the matter in the Universe would be cold neutrinos.
