Furaptra (Mag-Fura-2) tetrasodium salt ≥95% (por HPLC) indicador fluorescente, para determinação de cálcio
Supplier: Biotium
Mag-Fura-2 is a UV-excitable fluorescent indicator for magnesium with a Kd of 1.9 mM. Similar to Fura-2, the excitation wavelength of Mag-Fura-2 undergoes a blue shift from 369 nm to 330 nm. Mag-Fura-2 also responds to Ca2+ but with a significantly higher Kd than Fura-2 for Ca2+.

Sondas e colorações fluorescentes de terminais nervosos
Supplier: Biotium
Nerve terminal probes are a series of fluorescent cationic styryl dyes developed to follow synaptic activity. These dyes have a lipophilic tail at one end and a hydrophilic cationically charged head group at the other end. The dyes vary in the number of carbons in the lipophilic tail (m) and the number of double bonds linking the two aromatic rings in the dye (n). AM dyes are similar to FM dyes, but contain an additional formaldehyde-fixable amino group in the cationic head.

Substratos de coelenterazina para Renilla luciferase e apoaequorina
Supplier: Biotium
A Renilla luciferase catalisa a oxidação da coelenterazina para produzir luz, e é usado como uma enzima repórter, em ensaios baseados em luminescência. A Coelenterazina é um substrato natural para a Renilla luciferase, e mais de uma dúzia de análogos da coelenterazina foram sintetizados. Estes análogos podem funcionar como substratos da Renilla luciferase com diferenças na permeabilidade da membrana celular, na eficiência quântica e no comprimento de onda de emissão. O comprimento de onda de emissão é um factor importante quando a Renilla luciferase é usada combinada com uma proteína fluorescente tal como a GFP para a transferência de energia de ressonância bioluminiscente (BRET), uma aplicação importante para os estudos de interações proteína-proteína.

Ethidium homodimer I para coloração de núcleos
Supplier: Biotium
Ethidium Homodimer, first developed by Dr. Le Pecq and his colleagues, 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. The DNA binding of each Ethidium Homodimer covers four base pairs and is believed to occur by intercalation. Because the dye is highly positively charged, it cannot cross cell membranes to stain living cells. It is useful for detecting nucleic acids in solution, or for selectively staining dead cells with damaged plasma membranes.

SynaptoGreen™ C18 (Equivalent to FM®3-25) corante de membrana
Supplier: Biotium
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.

Reactive oxygen species indicators dyes
Supplier: Biotium
Dihydrorhodamine 123 is the reduced form of rhodamine 123, which is a commonly used fluorescent mitochondrial dye. It is non-fluorescent, but it readily enters most of the cells and is oxidized by oxidative species or by cellular redox systems to the fluorescent rhodamine 123 that accumulates in mitochondrial membranes. It is useful for detecting reactive oxygen species including superoxide (in the presence of peroxidase or cytochrome c) and peroxynitrite. Dihydrorhodamine 123 dihydrochloride is functionally equivalent to dihydrorhodamine 123 but with increased stability toward air oxidation and light during storage. Dihydroethidium (also called hydroethidium) is the chemically reduced form of the commonly used DNA dye ethidium bromide. The probe is useful to detect oxidative activities in viable cells, including respiratory burst in phagocytes. Dihydroethidium itself has blue fluorescence (355/420 nm) in cells, while the oxidized form ethidium has red fluorescence (518/605 nm) upon DNA intercalation. H2DCFDA (2′,7′-Dichlorodihydrofluorescein diacetate) is a useful fluorogenic reagent to detect reactive oxygen intermediates in cells. On oxidation, H2DCFDA becomes the highly green fluorescent 2′,7′-dichlorofluorescein, 504/529 nm (end product).
