Giemsa's stain solution 生物染色

Supplier: VWR Chemicals

Ethidium bromide solution is a fluorescent stain for visualising nucleic acids in solution or in electrophoresis gels. The solution is provided at a concentration of 0,625 mg/ml. A final working concentration of 0,5 g/ml is easily obtained by adding one drop of solution to 50 ml of molten agarose, running buffer or staining buffer. Ethidium bromide solution in dropper bottles may be stored at room temperature for up to one year.

Use this Coomassie brilliant blue R-250 solution to stain proteins in SDS-PAGE gels.

Supplier: VWR Chemicals

A pre-mixed dye solution used in cell culture applications to determine cell viability. A researcher can remove a sample of cells from culture and combine in a 1:1 ratio with the Trypan Blue solution. Under the microscope, dead cells will appear a blue color and viable cells will appear clear and translucent. Using a hemacytometer (gridded microscope slide), a researcher can quantify the percentage of dead cells within a population. Stained cells are ready for counting within five minutes.

Coomassie Brilliant Blue R-250 destaining solution.

Supplier: VWR Chemicals

Destaining bags are designed to safely remove ethidium bromide from solution during overnight treatment. Each bag extracts up to 5 mg of ethidium bromide from solution, thus minimising the exposure of research personnel to this toxic material. The special absorbent mixture retains dye molecules in a convenient bag for removal and incineration.

Zinc formalin fixative is a non-precipitating fixative. This fixative is compatible with histochemical, immunochemical and special stains. It may be used with automated tissue processors and also in manual methods. The zinc chloride component of the formulation increases the rigidity of cellular components to withstand subsequent processing, sectioning and staining procedures. Tissue specimens initially fixed using 10% neutral buffered formalin solution may be post-fixed using the zinc formalin fixative.
