Cell proliferation dyes diffuse passively into cells and covalently label intracellular proteins, resulting in long term cell labelling. They are non-fluorescent until they are hydrolysed by intracellular esterase's. The dyes then react with intracellular amines forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single, bright fluorescent population will be detected by flow cytometry. With each cell division, daughter cells inherit roughly half of the fluorescent label, allowing the number of cell divisions that occur after labelling to be detected by the appearance of successively dimmer fluorescent peaks on a flow cytometry histogram compared to cells analysed immediately after staining. Staining is formaldehyde fixable.

Wheat germ agglutinin binds specifically to N-acetylglucosamine in the peptidoglycan layer of gram-positive bacteria. The Live Bacterial Gram Stain Kit contains wheat germ agglutinin (WGA) conjugated to CF™594 to stain the surface of gram-positive cells with red fluorescence. The kit also includes DAPI to stain the DNA of all bacteria with blue fluorescence. Gram-positive bacteria stained using this kit will show a fluorescent blue interior and fluorescent red cell surface, while gram-negative bacterial will be stained with blue fluorescence only.

The Bacterial Viability and Gram Stain Kit contains three components: CF™488A-WGA, DAPI, and EthD-III solutions for distinguishing between gram-negative and gram-positive, as well as live versus dead bacteria.

TUNEL (terminal deoxynucleotidyl transferase (TdT) mediated dUTP nick-end labeling) is highly selective for the detection of apoptotic cells, but not necrotic cells or cells with DNA strand breaks resulting from irradiation or drug treatment. In this assay, TdT enzyme catalyses the addition of labeled dUTP to the 3’ ends of cleaved DNA fragments. Fluorescent dye-conjugated dUTP can be used for direct detection of fragmented DNA by fluorescence microscopy or flow cytometry.

RedDot™2 is a far-red cell membrane-impermeant nuclear dye similar to Draq7™. Ideal for staining the nuclei of dead or fixed and permeabilized cells with minimal cytoplasmic RNA staining.

Supplier: Biotium

RedDot™1 is a far-red cell membrane-permeable nuclear dye similar to Draq5™. The dye is ideal for specifically staining the nuclei of live cells.

WST-1 Proliferation Assay Kit provides an easy to use tool for studying the induction and inhibition of cell proliferation in any in vitro model. The assay is based on the reduction of tetrazolium salt WST-1 to soluble formazan by electron transport across the plasma membrane of dividing cells. This kit will also allow investigators to screen drug candidates involved in regulation of cell cycle.
