A procedure for the extensive purification of the Na(+)-coupled 5-hydroxytryptamine transporter of rat cerebral cortex has been developed. The 5-hydroxytryptamine transporter was solubilized with the non-ionic detergent digitonin, and the detergent extracts were subjected to sequential affinity chromatography on a citalopram-based agarose support and wheat-germ-agglutinin-Sepharose. 5-Hydroxytryptamine transporters in the affinity-purified preparation were identified by using the selective 5-hydroxytryptamine-uptake inhibitor [3H]paroxetine, and were shown to display a similar pharmacological profile to those present in particulate preparations. An overall transporter purification of around 2000-fold was achieved with a 9% recovery. SDS/PAGE of affinity-chromatographed material starting from detergent extracts incubated in the presence or absence of 1 mM-citalopram indicated that a polypeptide of M(r) 73,000 corresponded to the 5-hydroxytryptamine-transporter protein.
