-Log KD values determined from inhibition of [3H]CGP 12177 binding to intact C2C12 cells Values represent mean ± S.E.M. of -log KD values obtained from inhibition of the specific binding of [3H]CGP12177 (1 nM). Nonspecific binding was determined with 1 μM ICI 118551. n gives the number of separate experiments.
