Propidium monoazide
Based on 1 publication(s) in Google Scholar
Propidium monoazide is a cell-impermeant photoreactive DNA-binding dye that preferentially binds to dsDNA. Propidium monoazide (PMA) prevents DNA from dead bacteria from being amplified during the PCR. PMA-PCR enhanced both the specificity and the sensitivity of PCR. Propidium monoazide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

Guide (The following is the experimental plan we recommend. This plan serves only as a reference guide. The specific operations should be adjusted according to your actual needs.)
Propidium monoazide-PCR[1]
Propidium monoazide is used to label bacteria.
In a dimly lit room, add 5 μL of 2 mM photoreaction dye Propidium monoazide to 500 mL of the sample, resulting in a final concentration of 20 μM/μL.
2) Incubate the sample in the dark for 5 minutes (cover with aluminum foil), and gently shake the tube to ensure thorough mixing. Perform light activation with the PMA-LiteTM LED light source for 10 minutes.
2. Extract bacterial DNA
3. Perform PCR.
