Reactive DNA/RNA Binding Dyes
Amine reactive succinimidyl ester (SE) of nucleic acid dyes can be conjugated to proteins or other molecules with primary amine groups. The conjugates should be essentially nonfluorescent until they bind DNA or RNA, resulting in fluorescence. We also offer reactive methylene blue, a colorimetric DNA/RNA stain.
PMA, PMAxx™, and EMA are nucleic acid binding dyes that covalently react with DNA and RNA after photoactivation. They are useful for PCR-based quantitation of microbial viability (learn more about viability PCR).
