SYTOX
From Wikipedia, the free encyclopedia
SYTOX (also known as SYTOX Green) is a high-affinity nucleic acid stain developed by Molecular Probes. Because the stain only penetrates cells with compromised plasma membranes, it can be used to investigate antibacterial mechanism of action[1] and confirm loss of bacterial viability.[2][3] It can be used for live cell imaging of bacteria.[4]
SYBR Safe, SYBR Green, PicoGreen, SYTO-16, SYTO-9 and TOPhBu all can be used to detect DNA at low concentrations was evaluated using two new metrics, absolute fluorescence enhancement (AFE) and relativefluorescence enhancement (RFE).[5]
