Fluorescent dyes that simplify and improve your scientific experiments. For Microbiology, we offer a wide range of fluorescent dyes and assays kits to stain bacteria, yeast and fungi, including dyes to assess cell viability and bacterial gram stain type. We have also distribute a complete toolkit of reagents for viability PCR, a revolutionary method for determining microbial viability using qPCR.

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.
