Yeast Stains
Biotium offers a variety of dyes and stains that have been validated for use in yeast.
Organelle stains: MitoView™ dyes to stain mitochondria, LysoView™ dyes to stain the vacuole, Thiazole Orange to stain the nucleus.
Cell wall stains: Calcofluor White and Concanavalin A (ConA). Wheat Germ Agglutinin (WGA) localizes to bud scars.
Viability and metabolism: Live-or-Dye™ Fixable Live/Dead Kit, Viability Staining Kit with 3 color combos to choose from, and Vitality Staining Kit, containing the metabolic reporter ViaVac™ Red/Green (also available as a standalone dye).
ViaFluor® SE Cell Proliferation Kits
30139, 30139-T, 30068-T, 30068, 30086-T, 30086, - 30050View allHide
Fixable cytoplasmic stains for monitoring cell division by flow cytometry. The dyes can also be used to track cell populations in co-culture.
ViaVac™ Red/Green (FUN®1)
A fluorescent vitality dye for yeast, identical in structure to the dye FUN® 1. Living yeast cells show red fluorescent vacuolar tubules.
Yeast Live-or-Dye™ Fixable Live/Dead Staining Kit
A fixable, fluorescent assay to determine yeast viability. Contains two fluorescent components, Thiazole Orange and Live-or-Dye™ 568/583.
Yeast Viability Staining Kit
31063-1, 31063-2, - 31063-3View allHide
A rapid and selective fluorescent assay to determine yeast viability in microscopy or flow cytometry applications. Contains two fluorescent components, CF® Dye-labeled Con A and Live-or-Dye™.
Yeast Vitality Staining Kit
A fluorogenic assay that allows you to determine whether your yeast cells are metabolically active. Contains two fluorescent components, Calcofluor White and ViaVac™ Red/Green.
Calcofluor White Stain, 5 mM in Water
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 strongly stains bud scars.
Concanavalin A (Con A) CF® Dye Conjugates
29136, 29015, 29016, 29017, 29018, 29019, 29020, 29058, 29074, 29075, - 29080View allHide
A lectin labeled with our superior fluorescent CF® dyes is an effective and widely used cell surface stain for yeast, fungi, and mammalian cells.
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.
MitoView™ Mitochondrial Dyes
70070-T, 70070, 70054-T, 70054, 70055-T, 70055, 70075-50ug, 70075, 70068-T, - 70068View allHide
Fluorogenic mitochondrial stains for live cells that rapidly accumulate in mitochondria and can be imaged without washing.
Wheat Germ Agglutinin (WGA) Conjugates
29128-1, 29128, 29095-1, 29095, 29021, 29022, 29023, 29024, 29025, 29026, 29027, 29028, 29029, 29059, 29064, 29073, 29021-1, 29022-1, 29023-1, 29024-1, 29025-1, 29026-1, 29027-1, 29028-1, 29029-1, 29059-1, 29064-1, 29077-1, 29077, 29076-1, - 29076View allHide
A wheat germ agglutinin (WGA) lectin labeled with Biotium’s CF® Dyes, biotin, or HRP. It is a carbohydrate-binding lectin that has high affinity for sialic acid and N-acetylglucosamine and stains yeast bud scars as well as the cell membrane of gram+ bacteria and mammalian cells.
