  1. Calcium mobilization and PRESTO-Tango assay results of CCKBR. β values were calculated based on the EC50 and Emax from PRESTO-Tango and calcium mobilization assays, with CCK8s as reference. Values of EC50 and CCK8s maximal responses were shown as mean ± s.e.m. N, number of independently repeated experiments. Nil, no response or a biased factor that cannot be calculated.
