Fig. 3. The production of IP3 in female mouse vomeronasal organ (VNO)
membranes by male mouse urine. Reactions were performed without stimuli (PBS),
in the presence of 10% male urine, 100 µm GTP
S, 10% urine with
GDPßs, 10% male urine with pertussis toxin (PTX) and 10% male urine with
U73122. *Significantly different from control (PBS) value
