Nerve Terminal Staining Kits
70030, 70031, 70031-1, 70032, - 70034View allHide
Nerve Terminal Staining Kits contain Biotium’s nerve terminal dyes and accessories for washing away or quenching extracellular dye fluorescence.
SynaptoGreen™ C1
70042, - 70043View allHide
SynaptoGreen™ C1 has the shortest (one-carbon) lipophilic tail and is the most water soluble of the nerve terminal dye series. Thus it is expected to have the slowest on-rate and the fastest off-rate among the SynaptoGreen™ dyes.
SynaptoGreen™ C18 (Equivalent to FM®3-25)
70048, - 70049View allHide
SynaptoGreen™ C18 (equivalent to FM®3-25) is a membrane stain with a chemical structure similar to other nerve terminal dyes, except that it has the longest lipophilic tail (C18). Because of its large size, it is used as a control for ion channel permeability of nerve terminal dyes.
SynaptoGreen™ C2 (Equivalent to FM®2-10)
70044, - 70045View allHide
SynaptoGreen™ C2 is more water soluble than SynaptoGreen™ C4 and thus has a faster de-staining rate than the latter.
SynaptoGreen™ C3
70023, - 70026View allHide
SynaptoGreen™ C3 is similar to SynaptoGreen™ C4 (70020), except that the lipophilic tail is one carbon shorter and also the hydrophilic end is a trimethylammonium group.
SynaptoGreen™ C4 (Equivalent to FM®1-43)
70020, - 70022View allHide
A widely used green fluorescent dye for following synaptic activity by staining synaptic vesicles at the synapse or neuromuscular junctions. When used in combination with the red fluorescent dye SynaptoRed™ (70021), synapses or neuromuscular junctions can be imaged independently in two colors.
