Comparison of Advanced Cell Viability Analysis Methods

While flow cytometry remains the reference standard for detecting apoptosis and necrosis, its complexity, cost, and time requirements often limit its routine application. On the other hand, trypan blue staining is commonly used for its simplicity but lacks sensitivity in identifying early apoptotic events, which can affect data precision.

METTLER TOLEDO’s CytoDirect offers an innovative, stain-free approach. It rapidly and reliably assess cell viability based on morphological and biophysical cell properties. This method streamlines the workflow without compromising on sensitivity, particularly excelling in detecting subtle viability changes and early stages of cell death.

Through rigorous evaluation using diverse cell models—including Jurkat, HeLa, and primary PBMCs—our study demonstrates that CytoDirect provides results closely aligned with flow cytometry and often surpasses trypan blue in detecting early apoptotic cells and intermediate viability states. This is especially critical when working with heterogeneous samples like PBMCs, where traditional methods may struggle due to the complex nature of cell death progression.

CytoDirect not only delivers quantitative and visual insights but also enhances throughput, reproducibility, and operational simplicity, empowering researchers and clinicians to make informed decisions with confidence.

We understand that precise and timely cell viability assessment is vital to your work, and CytoDirect is designed to support your goals with accuracy and efficiency.
