Cell & Organelle Stains
RedDot™1 Far-Red Nuclear Stain, 200X in Water
40060-T, 40060, - 40060-1View allHide
A far-red live cell nuclear stain similar to Draq5™.
Ethidium Homodimer III (EthD-III)
A red fluorescent dead cell stain for bacteria and mammalian cells that is brighter than Ethidium Homodimer I.
Ethidium Bromide, 10 mg/mL in H2O
Ethidium bromide (EtBr) is a widely used nucleic acid gel stain although it is also a known potent mutagen. EtBr is an intercalating DNA-binding dye with little sequence preference.
Acridine Orange, 10 mg/mL in Water (High Purity) (AO)
Acridine orange (AO) stains dsDNA green (525 nm) and RNA or single stranded DNA red (650 nm). The dye is membrane-permeant and its nucleic acid binding property has been used for cell-cycle studies.
Ethidium Homodimer I (EthD-I)
40010, - 40014View allHide
A high purity grade, red fluorescent nucleic acid dye for detecting nucleic acids in solution or for selectively staining dead cells with damaged plasma membranes.
DMAO, 2 mM in DMSO
A membrane-permeable DNA dye, excellent for staining both gram positive and gram negative bacteria. Stained cells can be detected by fluorescence microscopy or flow cytometry.
DiO/DPA Membrane Potential Detection Kit
DiO/DPA is a highly sensitive FRET-based dye system that reports membrane potential change on submillisecond time scale.
JC-1 Mitochondrial Membrane Potential Detection Kit
30001, - 30001-TView allHide
JC-1 dye is used for fluorescence-based measurement of mitochondrial membrane potential changes in cells, a key measure of cell viability.
Biotin-cGMP, Diisopropylethylammonium Salt
00021, - 00021-1View allHide
A biotinylated cyclic nucleotide that is an important second messenger in many biological processes and has been used as a tracer in immunoassays.
Cyanine 644-cAMP
00022, - 00022-1View allHide
A fluorescently labeled cAMP analog that can be used to probe cAMP receptors.
Biotin-XX-α-Bungarotoxin
A high affinity inhibitor of the nicotinic acetylcholine receptor in the neuromuscular junction. Blocks acetylcholine activity at the postsynaptic membrane. The biotin conjugate can be subsequently labeled with anti-biotin antibodies, avidin, or streptavidin for signal amplification.
Biotin-cAMP
00020, - 00020-1View allHide
A biotin-conjugated cAMP analog that can be used to probe cAMP receptors.
α-Bungarotoxin
A high affinity inhibitor of the nicotinic acetylcholine receptor in the neuromuscular junction. Blocks acetylcholine activity at the postsynaptic membrane.
Calcein AM
80011, 80011-1, 80011-2, - 80011-3View allHide
Calcein AM is a widely used green fluorescent cell marker. Calcein AM is membrane-permeant and thus can be introduced into cells via incubation.
RH414
The styryl dye RH414 is a fast-responding potentiometric probe that is primarily used for functional imaging of neurons.
DASPEI
DASPEI (2-(4-(Dimethylamino)styryl)-N-ethylpyridinium iodide) is used to stain mitochondria in live cells.
