PMA (propidium monoazide) is a photo-reactive DNA-binding dye used in viability PCR (v-PCR) of microorganisms like bacteria, viruses, and fungi. PMA is available as a 1 mg lyophilized solid or 20 mM solution in water. Also try PMAxx™ (40069), a superior alternative to PMA.

• Selectively detect viable cells using qPCR
• Validated in hundreds of publications
• Dead cell specific dye, binds to DNA
• Covalently attaches to DNA after photoactivation
• Available as 1 mg lyophilized solid or 20 mM solution in water
• λ_Abs = 464 nm (before photolysis); λ_Abs/λ_Em= ~510/~610 nm (with DNA/RNA, after photolysis)
