Product name
FFN102 (Mini 102), Fluorescent DAT and VMAT2 substrate -
Description
Novel pH responsive FFN. Measures localization and activity of dopaminergic presynaptic terminals. -
Biological description
Novel, pH responsive fluorescent false neurotransmitter (FFN). Rodent DAT and VMAT2 substrate. Enables two-photon microscopic imaging of localization and activity of dopaminergic presynaptic terminals in the striatum of mouse acute brain slice. More selective for dopaminergic synapses than FFN511 (ab120331).
Exhibits greater fluorescence emission in neutral than acidic environments allowing optical measurement of synaptic vesicle content release.
Sufficiently bright, photostable and suitable for two-photon fluorescence microscopy and standard fluorescent microscopy. Compatible with GFP tags. -

Handling
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
