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

  • A broad range of color options, compatible with most instrument configurations
  • Different types of viability assays, designed to fit your experimental design
