Product Description

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.

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. In many species of yeast and fungi, in metabolically active cells the dye is actively transported into the vacuole, resulting in red fluorescent staining of tubular intravacuolar structures.

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.

After staining yeast with this kit, both living and dead cells will be outlined in blue, while only living cells will show red fluorescent, vacuolar tubules.

Kit Components (for 1000 assays):

  • ViaVac Red/Green, 10 mM in DMSO, 100 uL
  • Calcofluor White, 5 mM in water, 500 uL

    Yeast Viability Staining Kit

    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.

    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.
