AM1-43 Nerve Terminal Staining Kit IIA

Nerve terminal dyes have highly hydrophilic, cationically charged head groups at one end with lipophilic tails at the other end. They are virtually non-fluorescent in aqueous solution, but become intensely fluorescent in membranes. Following nerve stimulation, the dye molecules are internalized in newly formed endocytic vesicles. During exocytosis, the dyes are released from the vesicles along with neurotransmitters, causing a decrease in fluorescence signal. As a result, the change in fluorescent intensity reflects the amount of endocytosis/exocytosis or synaptic activity. Nerve Terminal Staining Kit IIA contains AM1-43 nerve terminal dye and ADVASEP-7 background reducing agent, a sulfonated cyclodextrin derivative for washing away or quenching extracellular dye fluorescence.
