Cell Viability Assays for Flow Cytometry

Dead cells often give false positive results as they tend to bind nonspecifically to many reagents. Therefore, removing dead cells from your flow cytometry data is a critical step to ensure accurate results and analysis. Molecular Probes® cell viability assays for flow cytometry help researchers distinguish live and dead cell populations more accurately than only using forward and side scatter characteristics.
