Mariano,
   Labvision has a very nice Rabbit Monoclonal antibody that works a charm.
It is RM-9106, but it looks like any of the polyclonal antibodies should
work in rat. Check out the following link:

Good Luck,
Amos

Hello all,

Could anybody recommend a good antibody to detect Ki-67 in rat tissues
(frozen) by fluorescence IHC?

Thank you!

Regards,
Mariano
