Product Description

The Yeast Viability Staining Kit is a fluorescent assay to determine yeast viability. Each kit contains two fluorescent components, CF® Dye-labeled Concanavalin A (ConA) and Live-or-Dye™ viability dye. There are 3 different color combinations to choose from (if there is a different color combination that you would prefer, email us at techsupport@biotium.com).

Live-or-Dye™ viability dyes are cell membrane impermeable amine-reactive dyes designed for discrimination between live and dead cells during flow cytometry or microscopy. They are able to enter into dead cells that have compromised membrane integrity and covalently label free amines on intracellular proteins. This dye labeling is extremely stable, allowing the cells to be fixed and permeabilized without loss of fluorescence or dye transfer between cells.

Concanavalin A (Con A) is a widely used lectin that selectively binds to a-mannopyranosyl and a-glucopyranosy residues, found in the cell wall of yeast and fungi. It is labeled with one of our superior bright, photostable CF® dyes.

After staining yeast with this kit, both living and dead cells will have cell walls stained with Con A, while only dead cells will also have the cytoplasm stained with Live-or-Dye™.

Kit Components (for 1000 assays):

  • Live-or-Dye™ (solid), 4 vials
  • Con A (solid), 5 vials
  • Anhydrous DMSO, 250 uL

Color Combinations:

  • Green/Red: CF®488A Con A & Live-or-Dye™ 594/614
  • Red/Blue: CF®594 Con A & Live-or-Dye™ 405/452
  • Far-Red/Red: CF®640R Con A & Live-or-Dye 568/583

    Yeast Vitality Staining Kit

    The Yeast Vitality Staining Kit is a fluorogenic assay that allows you to determine whether your yeast cells are metabolically active. The kit contains two fluorescent components, Calcofluor White and ViaVac Red/Green.

    Yeast Live-or-Dye™ Fixable Live/Dead Staining Kit

    The Yeast Live-or-Dye™ Fixable Live/Dead Staining Kit is a fixable, fluorescent assay to determine yeast viability. The kit contains two fluorescent components, Thiazole Orange and Live-or-Dye™ 568/583.

    ViaVac™ Red/Green

    ViaVac™ Red/Green is a fluorescent viability dye for yeast, identical in structure to the dye FUN® 1. ViaVac passively diffuses into cells, showing green cytoplasmic staining.

    Calcofluor White Stain, 5 mM in Water

    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.

    Thiazole Orange, 10 mM in DMSO

    Thiazole orange (TO) is commonly used in reticulocyte analysis to stain residual RNA of blood cells, to stain DNA in agarose gels and capillary electrophoresis. Thiazole Orange stains the yeast nucleus, and is also able to stain bacteria and mammalian cells.

    Concanavalin A (Con A) CF® Dye Conjugates

    This product is concanavalin A (Con A) labeled with our superior fluorescent CF® dyes. Con A is a widely used lectin that selectively binds to a-mannopyranosyl and a-glucopyranosy residues, found in the cell wall of yeast and fungi, and the cell membrane of mammalian cells.
