A new range of cell culture reagents which allows neuronal and other cells in culture to be kept alive during intense or prolonged exposure to light has been launched by Cell Guidance Systems.

LiveLight opens up new possibilities in the study and manipulation of cells

Cell culture is a core activity of neuroscience and other life science research. Cultured cells are usually grown in the dark and are only exposed to light for brief periods. However, cells sometimes need to be exposed to prolonged periods and/or high intensities of light. Such techniques include fluorescence activated cell sorting (FACS), live cell imaging, calcium imaging and optogenetics. Exposure to light in these experimental procedures can cause widespread cell death which impacts both interpretation of the experiment and restricts potential downstream applications. In large part, phototoxicity is due to components of the cell culture medium which are converted into toxic free radicals by exposure to light. To address this problem, LiveLight™ cell culture reagents have been specifically engineered to effectively eliminate the generation of free radicals. Components have also been added that stabilize the media. Using LiveLight™ reagents, even prolonged exposure of cells to intensive levels of light has negligible effects on cell survival. Now, sensitive cells, such as oligodendrocyte precursor cells, can maintain very high levels of viability.

LiveLight™ technology was developed by scientists at Cambridge University’s Stem Cell Institute. This technology has been exclusively licensed to Cell Guidance Systems. Dr Michael Jones, CEO of Cell Guidance Systems, commented “Phototoxicity is a significant issue in cell research, particularly for scientists working with neuronal cells. Many neuroscience experiments are compromised by free radicals that arise from components of standard media. LiveLight™ products have been engineered to eliminate these issues and open up new possibilities in the study and manipulation of cells.”
