Nerve Terminal Dyes
SynaptoGreen™ and SynaptoRed™ are nerve terminal dyes for tracking synaptic vesicle trafficking. Learn more about Nerve Terminal Dyes.
ViaVac™ Red/Green (FUN®1)
A fluorescent vitality dye for yeast, identical in structure to the dye FUN® 1. Living yeast cells show red fluorescent vacuolar tubules.
Nerve Terminal Staining Kits
70030, 70031, 70031-1, 70032, - 70034View 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.
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.
SynaptoGreen™ C5 (Equivalent to FM®1-84)
70046, - 70047View allHide
SynaptoGreen™ C5 is similar to SynaptoGreen™ C4 (70020), except that the lipophilic tail is one carbon longer.
70040, - 70041View allHide
SynaptoRed™ C1 is similar to the widely used red fluorescent nerve terminal dye SynaptoRed™ C2 (also called FM®4-64) except that the lipophilic tail of SynaptoRed™ C1 is one carbon shorter than that of the SynaptoRed™ C2.
SynaptoRed™ C2 (Equivalent to FM®4-64)
70021, - 70027View allHide
A widely used red fluorescent dye for following synaptic activity by staining synaptic vesicles at the synapse or neuromuscular junctions. When used in combination with the green fluorescent dye SynaptoGreen™ (70020), synapses or neuromuscular junctions can be imaged independently in two colors. SynaptoRed™ has also been used to study endocytosis in Dictyostelia.
SynaptoRed™ C2M (Equivalent to FM®5-95)
70019, - 70028View allHide
SynaptoRed™ C2M is a red fluorescent probe used to follow synaptic vesicles.
ADVASEP-7 is a sulfonated β-cyclodextrin derivative that has been reported to reduce background fluorescence when using SynaptoGreen C4 (also called FM1-43, catalog no. 70020) to stain brain slices.
AM1-43 (Equivalent to FM®1-43FX)
AM1-43 (equivalent to FM®1-43FX) is a fixable, activity-dependent fluorescent nerve terminal probe. AM1-43 functions similarly similarly to SynaptoGreen C4 (catalog # 70020), but with the additional property of being fixable.
AM1-44 is a version of AM1-43 (catalog no. 70024) with improved fixability. The dye can also be used as a general probe for following endocytosis.
AM2-10 is a fixable analog of SynaptoGreen™ C2.
AM3-25 is a lipophilic styryl dye that has an amine group at the hydrophilic head. The amine group reacts with formaldehyde or glutaldehyde to make the dye fixable.
