  Can you tell us why we can't co-localize?  Cindy B

We have a fellow in our lab who worked on QDs (quantum dots).
So I have learned that most QDs can be excitated under wave length
about between 400-600nm.
It means that you can use one certain wave length to excitate several
different QDs which are distinctive in emission wave length (thus
different in color). But the drawback is that you can not use two or
more QDs in order to see colocalization such as nucleus and membrane
molecules of the same cell.
