Cell Viability Assays for Flow Cytometry

Cell viability assays for flow cytometry are used for accurately distinguishing live and dead cell populations, helping ensure the precision of results and analysis. Removing dead and dying cells from your flow cytometry data is critical, as these cells can produce false positive results due to their compromised membranes which allow nonspecific binding and internalization of many reagents. Our flow cytometry viability stains are designed for both fixable and non-fixable cell samples and are available in a wide range of colors, helping ensure compatibility with most instrument configurations. These stains are an excellent choice for various research applications, including immunophenotyping, apoptosis studies, and cell cycle analysis.

Benefits of cell viability assays:

Enhanced accuracy and reliability of your flow cytometry data
Broad spectrum of color options for multi-parametric analysis
Compatibility with a wide range of flow cytometry instruments
Easy integration into existing workflows

Choose our high-quality viability stains to help improve the accuracy and reliability of your flow cytometry experiments. Explore our product range and find the right solution for your research needs in the selection guide below.
