The use of fluorescent dyes to identify cell structural components and monitor cytotoxicity or cellular responses to growth signals is well established. In addition to a wide selection of gold standard labeling dyes such as DAPI, Hoechst, and JC-1, Enzo Life Sciences has translated its expertise in fluorescent probe chemistry and cellular analysis into our CELLestial® portfolio of unique probe-based assays and reagents to meet the emerging needs of the life sciences and drug discovery markets. From simple organelle specific dyes for imaging cell structure and determining cell viability, to more complex dyes and reporter assays for monitoring cell signaling, death pathways, and toxicity, every product is developed and reliably manufactured to provide sensitivity, specificity, and convenience.
