Ghost Dyes™ - Fixable Viability Dyes
Exclude dead cells for accurate data!

  • Ready-to-use format
  • Easy to incorporate into staining protocols
  • Resistant to subsequent washing, fixation, & permeabilization

Ghost Dyes™ are amine reactive viability dyes that can be used to discriminate viable from non-viable mammalian cells in flow cytometry applications.

These dyes irreversibly bind free amines available on the cell surface as well as intracellular free amines exposed in cells with compromised cell membranes.

Necrotic cells with compromised membranes will react with significantly more Ghost Dyes™ than viable cells in the same sample and therefore will exhibit much greater fluorescence intensity allowing exclusion of these cells from analysis!

Enchant your research with trusted reagents!
Guaranteed to perform equivalently or better compared to other vendors!
