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.
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.
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.
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.
PMA Real-Time PCR Bacterial Viability Kit – Legionella pneumophila (mip)
A kit designed to perform viability PCR on Legionella pneumophila. It contains the viability PCR dye PMA and primers to amplify the mip gene.
CTC (5-Cyano-2,3-ditolyl tetrazolium chloride)
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.
PMAxx™ Dye, 20 mM in H2O
40069-1ML, - 40069View allHide
Viability PCR dye, a new and improved version of the popular viability dye propidium monoazide (PMA).

31051, - 31051-XView allHide
A kit designed to perform viability PCR on Listeria monocytogenes. It contains a viability dye (PMAxx™ or PMA) and primers to amplify the hly gene.
PMA Real-Time PCR Bacterial Viability Kit – E. coli (uidA)
31050, - 31050-XView allHide
A kit designed to perform viability PCR on E. coli. It contains a viability dye (PMAxx™ or PMA) and primers to amplify the uidA gene.
PMA Enhancer for Gram Negative Bacteria, 5X Solution
This product improves PMA- and PMAxx™-mediated discrimination between live and dead gram-negative bacteria when performing viability PCR.
PMA Real-Time PCR Bacterial Viability Kit – E. coli O157:H7 (Z3276)
31037, - 31037-XView allHide

PMA Real-Time PCR Bacterial Viability Kit – Mycobacterium tuberculosis (groEL2)
A kit designed to perform viability PCR on Mycobacterium tuberculosis. It contains the viability PCR dye PMA and primers to amplify the groEL2 gene.
PMA Real-Time PCR Bacterial Viability Kit – Staphylococcus aureus (nuc)
A kit designed to perform viability PCR on Staphylococcus aureus. It contains the viability PCR dye PMA and primers to amplify the nuc gene.
PMA Real-Time PCR Bacterial Viability Kit – Staphylococcus aureus (mecA)
A kit designed to perform viability PCR on MRSA. It contains the viability PCR dye PMA and primers to amplify the mecA gene.
PMA Real-Time PCR Bacterial Viability Kit – Salmonella enterica (invA)
31033, - 31033-XView allHide
A kit designed to perform viability PCR on Salmonella enterica. It contains a viability PCR dye (PMAxx™ or PMA) and primers to amplify the invA gene.
Viability/Cytotoxicity Assay Kit for Bacteria Live & Dead Cells
This kit provides two-color fluorescence staining of both live bacteria (green) and dead bacteria (red) using two DNA dyes, DMAO and EthD-III.
