Dead or dying cells in a sample can result in false positive events due to increased autofluorescence or non-specific binding to antibodies. Exclude dead cells from your analysis with one of our Zombie dyes. Unlike some viability dyes, Zombie dyes are fixable, making them ideal for flow panels that include intracellular markers. With seven different Zombie dyes available, they can easily fit into your multicolor panels.
 

Zombie dyes react with primary amine groups on proteins. Live cells exclude the dye so only cell surface proteins are labeled. The dye can enter dead cells increasing the total protein labeling and creating a significantly brighter signal.
