FSU:Fluorescence Sensitivity Units; PBS:phosphate-buffer-saline; 5-HTTP:5-hydroxytryptophan; PF-5-HTTP:5-hydroxytryptophan tagged with multiple-fluorine atoms. Values with the same letters (a, b) were not significantly different at probability level 0.05 as determined by one-way analysis of variance with the Student-Newman-Keuls multiple-comparison test. |
