Summary

Automatic Translation

Este manuscrito descreve como para o rastreio de mutações thermostabilizing, purificar o transportador humano de serotonina, gerar anticorpos de elevada afinidade, e cristalizar o complexo transportador-anticorpo serotonina ligada ao -citalopram S droga antidepressiva. Este protocolo pode ser adaptado para o estudo de outros transportadores difíceis de membrana, receptores e canais.
