I in vitro studier var IC50- værdierne for serotonin transportør og KATP kanaler 7 respektive 12 gange højere end EC50 værdi for kalciumreceptoren ved lige forsøgbetingelser.
In in vitro studies, IC50 values for the serotonin transporter and KATP channels were found to be 7 and 12 fold greater, respectively, than the EC50 for the calcium-sensing receptor obtained under the same experimental conditions.
