Cell Cycle Assay Cell-Clock™


The Cell-Clock Cell Cycle Assay is a live cell detection and measurement system that can be employed to monitor the four major phases of the mammalian cell cycle during in vitro culture. The assay uses a redox dye that is imported by cycling cells.

Following dye uptake and incubation a distinct colour change occurs within cells, with particular colour changes being associated with cells in the G0-G1, S, G2 and M Phases.

The ratio of cells within the different phases can be calculated using this assay supplemented by visible evidence from photomicrographs.  The calculation of phase ratios is obtained by computer software analysis (ImageJ) of the digitised images of photomicrographs.
