Microbiology
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.

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.
Acridine Orange, 10 mg/mL in Water (High Purity) (AO)
Acridine orange (AO) stains dsDNA green (525 nm) and RNA or single stranded DNA red (650 nm). The dye is membrane-permeant and its nucleic acid binding property has been used for cell-cycle studies.
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.
Ethidium Bromide, 10 mg/mL in H2O
Ethidium bromide (EtBr) is a widely used nucleic acid gel stain although it is also a known potent mutagen. EtBr is an intercalating DNA-binding dye with little sequence preference.
Hoechst
