Specification:

Uses:Propidium iodide is a membrane impermeable red fluorescent nucleic acid dye widely used in cell 

biology and microbiology research to evaluate cell viability and nucleic acid status. Its core characteristic is 

that it can only enter cells with membrane damage, and after binding with DNA/RNA, it emits strong 

red fluorescence, which is a key tool for determining cell death and cycle analysis.
