Judy,

colocalization analysis is quite straight forward with ImageJ and the
"Colocalisation Threshold" plus "Colocalization Test" plugin according to
Costes.

Regarding triple labeling, which type of questions do you plan to answer?
I can think about a scenario with two marked structures and how they are
colocalizing with the nuclei - then you do two runs: nuclei vs. staining
1, nuclei vs. staining 2. I am not aware of an established three-color
colocalization equation. Or do I miss something here?
