Fd Neurotechnologies Inc FD Rapid TimmStain™ Kit

Timm’s sulphide silver method has so far been considered a very sensitive technique for demonstrating metal ions, in particular zinc in the central nervous system. The principle of this technique is that metals in the tissue can be transformed histochemically to metal sulphides. Subsequently, metal sulphides catalyze the reduction of silver ions by a reducing agent to metallic grains that are visible under a light or electron microscope.

Biotium DPA

Dipicrylamine (DPA) is a nonfluorescent anionic membrane dye. With its absorbance in the blue region of the visible spectrum, DPA can be used as a FRET quencher for a variety of fluorescent donor dyes. When applied to cells, DPA localizes at the interface of cytoplasmic membrane and aqueous phase in a manner sensitive to membrane potential change. A recent application of DPA is to measure cell membrane potential change by combining with the fluorescent donor dye DiOC16. The DiO/DPA system has been reported to produce a fluorescence signal change of >56% in HEK-293 cells and >25% in neuronal cultures and brain slices per 100 mV membrane potential change. Please also see the DiO/DPA Membrane Potential Detection Kit. Properties: Yellow solid soluble in DMSO at >30mg/mL; Abs. (MeOH) = 406 nm; Store at 4°C; MWt: 439.21; [131-73-7]

Biotium DAPI

DAPI (4′,6-Diamidino-2-Phenylindole, dihydrochloride) is a popular blue DNA dye that is used as a nuclear counterstain in fluorescence microscopy, chromosome staining and flow cytometry. The dye binds to the minor groove of dsDNA with approximately 20-fold fluorescence enhancement, with higher affinity for A-T rich regions. DAPI may be used in fixed cells or in live cells at higher concentrations. The dye has an excitation/emission of 358/461 nm. Properties: Yellow solid soluble in water; Store dessicated at 4°C, protect from light; Ex/Em= 358/461 nm (with DNA); C16H17Cl2N5; MW:350.25; [28718-90-3].

Biotium BactoView™ Live Red

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 Red can be detected in the PE-Cy5 channel for flow cytometry, and the Cy3 channel for microscopy. Properties: Liquid; Ex/Em= 572/675 nm; Store at 4°C and protect from light.
