(A) In vivo imaging of Cox-2luc/+ and Cox-2luc/- mice. Each mouse was injected with zymosan in the right rear paw and PBS in the left paw, then anesthetized, injected with luciferin, and imaged at time shown following zymosan injection. (B) Luciferase activities, as photon number, are shown for zymosan-injected paws of each mouse.
