FFN511 是一种靶向神经元囊泡单胺转运体 2 (VMA T2) 的荧光假神经递质 (FFNs)。FFN511 可抑制 5-羟色胺与含 VMA T2 的膜结合，其 IC50 值为 1 µM。FFN511 能直接反映细胞外渗过程中的释放动态，可用于标记活体皮质-纹状体急性切片中的多巴胺能神经末梢。 FFN511 is a potent fluorescent false neurotransmitters (FFNs) that targets neuronal vesicular monoamine transporter 2 (VMA T2). FFN511 inhibits serotonin binding to VMA T2-containing membranes with an IC50 of 1 µM. FFN511 directly images the dynamics of release during exocytosis, can be used to label dopamine terminals in live cortical-striatalacute slices。
