5(6)-Carboxyrhodamine 110-X succinimudyl ester ≥90% (by TLC) amine-reactive fluorescent dye

Catalog Number: (90003.)
Supplier: Biotium
Description: 5-(and-6)-Carboxyrhodamine 110-X, succinimidyl ester (5(6)-CR 110-X, SE) readily couples to a primary or secondary amine. The dye is a superior alternative to 5(6)-SFX because of its exceptional phototostability and fluorescence insensitivity to pH (4-9).
UOM: 1 * 5 mg

3,3'-Diethylthiadicarbocyanine iodide [DiSC₂(5)] ≥95% (by TLC) DNA/RNA binding dye

Catalog Number: (40041.)
Supplier: Biotium
Description: DiSC2(5) (3,3′-Diethylthiadicarbocyanine, iodide) binds to DNA-DNA or PNA-DNA duplexes with a large blue-shift of the absorption spectrum. Binding of the dye to PNA-DNA hybrid, in particular, blue-shifts the dye absorption spectrum by as much as 115 nm, offering a visual method to detect nucleic acid hybridization.

Menadione sodium bisulphite ≥95% (by TLC), Sigma-Aldrich®

Supplier: Merck
Description: Water soluble vitamin K3.

Image Unavailable-59006.

4-Bromo-A-23187 free acid ≥98% (by TLC, NMR) ionophore, for calcium determination

Catalog Number: (59006.)
Supplier: Biotium
Description: Similar to A-23187, 4-Bromo A-23187 is used for in situ calibrations of fluorescent Ca2 indicators to equilibrate intracellular and extracellular calcium concentrations and to allow Mn2 to enter cells to quench indicator fluorescence. However, since 4-bromo A-23187 is nonfluorescent, it is preferred over the blue fluorescent A-23187 for calibrations of UV-excited Ca2 indicators such as Indo-1 and Fura-2 in order to keep background fluorescence to a minimum.
UOM: 1 * 1 mg

Potassium-4-nitrophenyl sulphate ≥98% (by TLC), Sigma-Aldrich®

Supplier: Merck
Description: Chromogenic sulphatase substrate.

Image Unavailable-51017.

5-Carboxy-2',7'-dichlorofluorescein ≥98% (by TLC) fluorescent pH indicator

Catalog Number: (51017.)
Supplier: Biotium
Description: This dye can be used as a low pH indicator similar to 51015, and is also useful as a general green fluorescent label. Carboxy-2′,7′-dichlorofluorescein is significantly more photo-stable than carboxyfluorescein.
UOM: 1 * 100 mg
Image Unavailable-90004.

5(6)-Carboxy-X-rhodamine triethylammonium salt ≥98% (by TLC) amine-reactive fluorescent dye

Catalog Number: (90004.)
Supplier: Biotium
Description: 5(6)-ROX (full name: 5-(and-6)-Carboxy-X-rhodamine, triethylammonium salt (mixed isomers)) is a long wavelength rhodamine dye.
UOM: 1 * 25 mg

6-Cyano-7-nitroquinoxaline-2,3-dione disodium salt, disodium salt ≥98% (by TLC)

Supplier: ENZO LIFE SCIENCES
Description: AMPA/kainate receptor antagonist

Image Unavailable-51023.

5-Carboxy-2',7'-dichlorosulphonefluorescein ≥98% (by TLC) fluorescent pH indicator

Catalog Number: (51023.)
Supplier: Biotium
Description: The pKa of 5-carboxy-2′,7′-dichlorosulfonefluorescein is near 4 and thus the dye is potentially an excellent pH indicator for acidic organelles.
UOM: 1 * 10 mg
Image Unavailable-50004.

5,5′-Dibromo BAPTA tetrapotassium salt ≥95% (by TLC) ion chelator, for calcium determination

Catalog Number: (50004.)
Supplier: Biotium
Description: BAPTA and its derivatives are calcium chelators that are commonly used to form calcium buffers with well-defined calcium concentrations. By injecting the chelators into cells or by incubating cells with the AM ester form of the chelators, one can control the cytosolic calcium concentration, an important means to study the roles of calcium.

6-Carboxyfluorescein-N-succinimidyl ester (6-FAM SE) ≥99% (by TLC) amine-reactive fluorescent dye

Catalog Number: (90023.)
Supplier: Biotium
Description: 6-FAM, SE (full name: 6-Carboxyfluorescein, succinimidyl ester, single isomer) is the amine-reactive form of 6-carboxyfluorescein single isomer.
6-FAM SE is an amine-reactive green fluorescent dye widely used for labeling oligonucleotides or other biomolecules that contain a primary or secondary aliphatic amine. The coupling reaction is usually carried out at pH 8-9.5.
UOM: 1 * 10 mg
Image Unavailable-SIAL86339-1G

Sodium taurocholate hydrate ≥97.0% (by TLC), Sigma-Aldrich®

Supplier: Merck
Description: Sodium taurocholate hydrate is used as an emulsifier in <i>in situ</i> preparation of digestive enzymes.

5,5’-Dimethyl BAPTA AM ester ≥95% (by TLC) ion chelator, for calcium determination

Catalog Number: (50007.)
Supplier: Biotium
Description: Dimethyl BAPTA AM ester is a membrane permeable form of Dimethyl BAPTA that can be loaded into cells by incubation. Dimethyl BAPTA AM ester itself does not bind calcium, but once inside the cell is converted into Dimethyl BAPTA by cytoplasmic esterases.
UOM: 1 * 25 mg
