| | Radioligand Binding Assay |
| Description: | The pharmacological profile of metopimazine, metopimazine acid (MPZA), domperidone, and metoclopramide were assessed by radioligand binding and by a functional antagonist assay. For the radioligand binding assay, cell membranes of dopamine D2 receptor expressing cells were incubated with [3H]spiperone and competing drugs in buffer. The assay was terminated by rapid filtration, and the bound radioactive signal was determined by liquid scintillation counting. |
