We are trying to inject a compound into a live mouse.
After 2 days the animal will be sacrificed and histology
performed.  To ensure that the injections reached the
appropriate site, we want to include a dye with the fluid
for identification.

Does anyone know of a stain which would be easily
visible yet not interfere with the normal metabolism
of the cells.

Thank you.
