PMA qPCR live bacteria detection kit (without primer) is utilized in microbiology and biomedical research for detecting viable bacteria through quantitative polymerase chain reaction (qPCR) techniques Originating from advancements in molecular biology the kit employs propidium monoazide (PMA) to selectively penetrate and modify the DNA of dead cells preventing their amplification while allowing qPCR to target only live cells This differentiation is crucial for accurate viability studies often showing efficacy in the nanomolar to low micromolar range during in vitro assessments Common applications include microbial viability studies drug screening and validation of bacterial presence in various samples using cell models or animal studies Experimental concentrations typically depend on the specific research design ensuring the kit s versatility in addressing diverse research needs
