Fd Neurotechnologies Inc FD RAPID GOLGISTAIN KIT SMALL

Using the Golgi technique, subtle morphological alterations in neuronal dendrites and dendritic spines have been discovered in the brains of animals treated with drugs as well as in the postmortem brains of patients with neurological diseases3, 4. However, the unreliability and the time-consuming process of Golgi staining have been major obstacles to the widespread application of this technique. FD Rapid GolgiStain™ Kit is designed based on the principle of the methods described by Ramón- Moliner2, Glaser and Van der Loos5. This kit has not only dramatically improved and simplified the Golgi-Cox technique but has also proven to be extremely reliable and sensitive for demonstrating morphological details of neurons and glia, especially dendritic spines. The FD Rapid GolgiStain™ Kit has been tested extensively and widely used on the brains from several species of animals as well as on the specimens of postmortem human brains

Biotium Calcofluor White Stain, 5 mM in Water. 20ml

Calcofluor White is a fluorescent blue dye that binds to cellulose and chitin, which can be found in the cell walls of fungi, algae, and plants. In budding yeast Calcofluor White stains bud scars more strongly, because they have a higher concentration of chitin. Calcofluor White is sometimes used to identify fungal infections in medical samples. Calcofluor White also stains gram-positive bacteria, but not gram-negative bacteria or mammalian cells. Properties: Provided as a 5 mM solution in water; Ex/Em 360/430 nm; Store at -20¿C, protected from light; C40H44N12O10S2; MW: 916.98

Biotium ViaFluor 488 SE Cell Proliferation Kit (10 vials, 1000 assays)

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 488 SE which has an excitation/emission of 493/532 nm. The kit contains 10 lyophilized dye vials. Each vial is sufficient for 20 uL of 5000X stock solution.
