Used for detecting and quantifying polyphosphate kinase (PPK) enzyme activity in microbial samples, this ELISA kit supports research in bacterial metabolism, stress response, and biofilm formation. It enables scientists to study the role of polyphosphate synthesis in pathogens, aiding in the development of antimicrobial strategies. The kit is also applied in environmental microbiology to assess microbial nutrient storage and energy dynamics in soil and water systems. Its high sensitivity allows for precise measurement in small sample volumes, making it suitable for high-throughput screening in drug discovery and functional genomics studies.
