TABLE 1

[3H]fenobam and [3H]MPEP binding properties at human and rat mGlu5 Saturation binding isotherms of [3H]fenobam and [3H]MPEP were performed on membrane preparations from HEK-293 cells transiently transfected with the human and rat mGlu5 receptors as described under Materials and Methods. Values are mean ± S.E.M. of the Kd and Bmax values, calculated from three independent experiments (each performed in triplicate).
