We would be very grateful if those of you who in vivo label bone would share
your experiences with us.  We are currently looking at both ground and thin
(5-8µ) sections of oxytetracycline labeled bone.  The crisp lines we were
hoping for and see in all the published articles are rarely there.  Is this
a microscopy or preparation related issue?

Thanks,
