Extended Data Table 1 Binding to the R0 and RG states of the PTHR. Reported are ligand concentrations that inhibited binding of radioligand by 50% (IC50). Data are the mean value ± s.e.m. of n = 4 (R0 state), and n = 5 (RG state), each in duplicate. P values are pairwise comparison (Student’s t-test, two-sided) to PTH.
