Hi Nora,

The doses for XO is 90/mg/kg/day SQ.  XO is not as bright as calcein, if animals are forming bone very slowly you may want to consider injecting for 2 days in a row.

First, thanks to all who responded to my question on this earlier.

We are interested in using xylenol orange as a fluorochrome label for bone.
Two references give very different doses, specifically, 90 mg/kg & 90
ng/kg.  Has anyone ever used this label?  Does anyone know what the correct
amount is?

Thanks in advance.
