Cell & Organelle Stains

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 is more water soluble than SynaptoGreen™ C4 and thus has a faster de-staining rate than the latter.

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.

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 is similar to SynaptoGreen™ C4 (70020), except that the lipophilic tail is one carbon longer.

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.

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 is a red fluorescent probe used to follow synaptic vesicles.

Thiazole Green, which is structurally identical to SYBR® Green I Nucleic Acid Gel Stain, is one of the most sensitive stains available for detecting double-stranded DNA (dsDNA) in agarose, polyacrylamide gels and qPCR.

Thiazole Orange Homodimer (TOhD), also known as TOTO®-1, is a cell-impermeant, high-affinity, fluorogenic green nucleic acid stain.

Thiazole orange (TO) is commonly used in reticulocyte analysis to stain residual RNA of blood cells, to stain DNA in agarose gels and capillary electrophoresis. Thiazole Orange stains the yeast nucleus, and is also able to stain bacteria and mammalian cells.

Thiazole Red, also known as TO-PRO®-3, is a cell-impermeant, high-affinity far-red nucleic acid stain.

Thiazole red homodimer (TRhD), also known as TOTO®-3, is a cell-impermeant, high-affinity, far-red fluorogenic nucleic acid stain.

TO Iodide, also known as TO-PRO®-1, is a green fluorescent, cell-impermeant nucleic acid stain that can be used to stain dead or fixed cells.

Labeled human transferrin is used for microscopic studies of the endosomal pathway and/or transferrin uptake studies.

Highly-selective dead cell stains for bacteria cultures. The stains are suitable for both gram-positive and gram-negative strains.
