alpha-Methyl tryptophan as a tracer for in vivo studies of brain serotonin system, from autoradiography to positron emission tomography
Abstract
The procedure for measuring the brain serotonin synthesis rate in living brain using labelled alpha-methyl-L-tryptophan (alpha-MTrp), a tryptophan analog, is described. This tracer could also be used for the anterograde axonal transport measurement of serotonin. One advantage of this method is that alpha-MTrp is converted in situ into a serotonin tracer, alpha-methyl serotonin, and should be distributed into the same compartments as serotonin.
