Biotium ViaFluor CFSE Cell Proliferation Kit

ViaFluor SE Cell Proliferation Kits use non-toxic, amine-reactive dyes to covalently label cells throughout the cell cytoplasm and intracellular compartments. Cell proliferation dyes are commonly 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. Labeling is covalent, so it withstands fixation and permeabilization for subsequent immunostaining. This kit contains ViaFluor CFSE which has an excitation/emission of 495/519 nm. The kit contains 10 lyophilized dye vials. Each vial is sufficient for 18 uL of 5000X stock solution.

Biotium BactoView™ Live Green

BactoView™ Live dyes are fluorogenic live cell bacterial stains. The stains are bright and cell-permeable, they are able to stain both gram-positive and gram-negative bacteria. Stained cells can be detected by fluorescence microscopy or flow cytometry. BactoView™ Live dyes can stain both live and dead bacteria, though dead cells tend to stain a bit brighter than live cells. BactoView™ Live Green can be detected in the FITC channel for flow cytometry and microscopy. Properties: Liquid; Ex/Em= 500/520 nm; Store at 4°C and protect from light.

Biotium NucSpot Live 650, 1000X in DMSO

NucSpot Live Cell Nuclear Stains are cell-membrane permeable DNA dyes that specifically stain nuclei in live or fixed cells. They have excellent specificity for DNA without the need for a wash step, and they have low toxicity for live cell imaging. The dyes are supplied as 1000X stock solutions in DMSO, and are supplied with a vial of verapamil, which may increase probe retention and staining in some cell types. NucSpot Live 650 stains nuclei with far-red fluorescence and has an excitation/emission of 650/675 nm for detection in the Cy5 channel. Properties: Ex/Em= 650/675 nm; Store at 4°C and protect from light.

Biotium Hydroxystilbamidine, 4% in H2O

Hydroxystilbamidine (also called Fluoro-Gold) has been used extensively as a retrograde tracer for neurons and also a histochemical stain. Fluoro-Gold can undergo retrograde axonal transport, it shows extensive filling of dendrites, and has a high resistance to fading. The 4% solution in deionized H2O is a convenient, ready-to-use form. If desired, the solution can be diluted to a lower concentration. For most applications, the typically dye concentration is 2% to 4%. We also sell hydroxystilbamidine in solid form. Properties: Ex/Em = 361/536 nm; Store at 4°C and protect from light; C18H24N4O7S2; MWt: 473; [223769-64-0].Fluoro-Gold is a trademark of Fluorochrome, LLC.

Biotium Ethidium Homodimer I

Ethidium Homodimer I (EthD-1) is a high-affinity fluorescent nucleic acid stain. It binds to both DNA and RNA in a sequence-independent manner and with a >30-fold fluorescence enhancement. It is useful for detecting nucleic acids in solution, or for selectively staining dead cells with damaged plasma membranes. Biotium offers Ethidium Homodimer I in much higher purity than other manufacturers. The dye has an excitation/emission of 528/617 nm when bound to DNA. Properties: Red solid soluble in water or DMSO; Store dessicated at 4°C, protect from light; Ex/Em = 528/617 nm (with DNA); C46H50Cl4N8; MW:857; [61926-22-5].
