    Calcofluor White Stain, 5 mM in water

    From: $50 Sizes: 20 mLCatalog #: 29067

    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.

    CTC (5-Cyano-2,3-ditolyl tetrazolium chloride)

    From: $47 Sizes: 10 mgCatalog #: 10063

    5-Cyano-2,3-ditolyl tetrazolium chloride (CTC) has been used to evaluate the respiratory activity of many bacterial populations as well as populations undergoing drug efficacy evaluations.  Healthy cells respiring via the electron transport chain will absorb and reduce CTC into an insoluble, red fluorescent formazan product.
