Cell & Organelle Stains

NucSpot® Live Cell Nuclear Stains are cell-membrane permeable DNA dyes that specifically stains nuclei in live or fixed cells. They have excellent specificity for DNA without the need for a wash step, and they have have low toxicity for live cell imaging. Supplied as 1000X stock solutions in DMSO.

CellBrite™ Fix Membrane Stains are a new class of fluorogenic membrane dyes that covalently stain the plasma membrane in live cells. They are unique among membrane stains in that they can withstand both fixation and detergent permeabilization. Available with green, red, and far-red fluorescence.

MemBrite™ Fix Cell Surface Staining Kits provide a convenient way to visualize cell boundaries in multicolor staining experiments. Staining is rapid and uniform, with a wide choice of colors. MemBrite™ Fix dyes covalently label the surface of live cells. The staining withstands fixation and permeabilization for subsequent immunofluorescence staining.

NucSpot® 470 is cell membrane-impermeant, nuclear-specific green fluorescent DNA stain for the FITC channel.

RedDot™1 is a far-red cell membrane-permeable nuclear dye similar to Draq5™. The dye is ideal for specifically staining the nuclei of live cells.

RedDot™2 is a far-red cell membrane-impermeable nuclear dye similar to Draq7™, with excitation and emission at 665/695 nm. The dye is ideal for specifically staining the nuclei of dead cells with minimal cytoplasmic RNA staining.

ViaFluor® Live Cell Microtubule Stains are cell-permeable taxol probes for imaging the microtubule cytoskeleton in live cells. Available with blue, green, or far-red fluorescence.

ViaFluor® SE Cell Proliferation Kits use amine-reactive dyes to covalently label the cell cytoplasm, and are used to monitor cell division by flow cytometry. The dyes also can be used to stably label cells to image cell morphology, or to track cell populations in mixed co-culture experiments. The labeling withstands fixation and permeabilization for immunostaining.

CellBrite™ Cytoplasmic Membrane Labeling Kits are designed to label cell cytoplasmic membranes with fluorescent dyes, available in blue, green, orange, and red. The labeling is stable and nontoxic, suitable for long-term tracking of cells.

Biotium’s CellBrite™ NIR Cytoplasmic Membrane Dyes are ready-to-use dye delivery solutions that can be added directly to normal culture media to uniformly label cells in suspension or adherent cultures.

Our CF® dye hydrazides are bright, extremely water-soluble and nontoxic. These properties make the dyes excellent fixable polar tracers for neurons, or for gap junction studies.

LipidSpot™ Dyes rapidly stains lipid droplets in live cells or fixed cells, with no wash step required. Available with green or red/far-red fluorescence.

LysoView™ dyes label lysosomes in live cells, and are available with blue, green, visible red, and far-red fluorescence. Far-red LysoView™ 650 is compatible with super-resolution imaging by STED and SIM. Note: LysoView™650 (70059 and 70059-T) is temporarily unavailable.

Conjugates of α-Bungarotoxin labeled with a selection of our CF® dyes and other labels. Labeled α-bungarotoxin conjugates can be used for staining nicotinic acetylcholine receptors at neuromuscular junctions in tissue sections.

CF® dye bovine serum albumin (BSA) are bright and photostable fluorescent BSA conjugates for applications in which well-defined molecular weight fluid phase tracers are needed. These applications include studying the rate of endocytosis and exocytosis and following vesicle trafficking.

CF®488A-cAMP and CF®640R-cAMP are fluorescently labeled cAMP analogs. Single molecules of fluorescently labeled cAMP have been imaged bound to the cAMP receptor on the surface of Dictyostelium cells (1).
