Cell Meter™ Fluorimetric Live Cell Cycle Assay Kit *Green Fluorescence Optimized for Flow Cytometry*
Our Cell Meter™ assay kits are a set of tools for monitoring cell viability and proliferation. There are a variety of parameters that can be used for monitoring cell viability and proliferation. In normal cells, DNA density changes depending on whether the cell is growing, dividing, resting, or performing its ordinary functions. The progression of the cell cycle is controlled by a complex interplay among various cell cycle regulators. These regulators activate transcription factors, which bind to DNA and turn on or off the production of proteins that result in cell division. Any misstep in this regulatory cascade causes abnormal cell proliferation which underlies many pathological conditions, such as tumor formation. Potential applications for live-cell studies are in the determination of cellular DNA content and cell cycle distribution for the detection of variations in growth patterns, for monitoring apoptosis, and for evaluating tumor cell behavior and suppressor gene mechanisms. This particular kit is designed to monitor cell cycle progression and proliferation using our proprietary Nuclear Green™ LCS1 in live, permeabilized and fixed cells. The percentage of cells in a given sample that are in G0/G1, S and G2/M phases, as well as the cells in the sub-G1 phase prior to apoptosis can be determined by flow cytometry. Cells stained with Nuclear Green™ LCS1 can be monitored with a flow cytometer (FL1 channel).
Example protocol

Protocol Summary
- Prepare cells with test compounds at a density of 5 × 105 to 1 × 106 cells/mL
- Add 2.5 µL of 200X Nuclear Green™ LCS1 into 0.5 mL of cell solution
- Incubate at 37°C, 5% CO2 incubator for 30 - 60 minutes
- Analyze cells with a flow cytometer using 530/30 nm filter (FITC channel)

SAMPLE EXPERIMENTAL PROTOCOL
- For each sample, prepare cells in 0.5 mL of warm medium or buffer of your choice at a density of 5 × 105 to 1 × 106 cells/mL.
Note Each cell line should be evaluated on an individual basis to determine the optimal cell density for apoptosis induction. - Treat cells with test compounds for a desired period of time to induce apoptosis or other cell cycle functions.
- Add 2.5 µL of 200X Nuclear Green™ LCS1 (Component A) into the treated cells.
- Incubate the cells in a 37°C, 5% CO2 incubator for 30 to 60 minutes.
Note For adherent cells, gently lift the cells with 0.5 mM EDTA to keep the cells intact, and wash the cells once with serum-containing media prior to incubation with Nuclear Green™ LCS1. The appropriate incubation time depends on the individual cell type and cell concentration used. Optimize the incubation time for each experiment. It is not necessary to fix the cells before DNA staining since the Nuclear Green™ LCS1 is cell-permeable. - Optional: Centrifuge the cells at 1000 rpm for 4 minutes, and then re-suspend cells in 0.5 mL of assay buffer (Component B) or the buffer of your choice.
- Monitor the fluorescence intensity using a flow cytometer using 530/30 nm filter (FITC channel). Gate on the cells of interest, excluding debris.
