Furaptra (Mag-Fura-2) tetrasodium salt ≥95% (by HPLC) fluorescent indicator, for calcium determination

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+.

Ethidium homodimer I used in nuclear staining

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.

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).

Fluorescenční nervové terminální sondy a skvrny

Fluorescenční nervové terminální sondy a skvrny

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.

SynaptoGreen™ C18 (Equivalent to FM®3-25) membrane stain

SynaptoGreen™ C18 (Equivalent to FM®3-25) membrane stain

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.

Bungarotoxins and fluorescent bungarotoxin conjugates

Bungarotoxins and fluorescent bungarotoxin conjugates

Supplier: Biotium

Bungarotoxins are venom toxins from the many-banded krait (Bungarus Multicinctus), which inhibit neurotransmission at the neuromuscular junction. Alpha-bungarotoxin is a potent inhibitor for the motor endplate acetylcholine receptor (Kd = 1 nM to 1 pM). Beta-bungarotoxin contains a small subunit that blocks voltage-gated K+ channels on the presynaptic membranes, and a large subunit that has phospholipase A2 activity. Fluorescent conjugates of alpha-bungarotoxin can be used to label acetylcholine receptors in skeletal muscle endplates.
