Used in research settings to quantify microbial polyphosphate hydrolase (PPX) enzyme levels in biological samples. Enables detection and measurement of PPX activity in environmental, industrial, and clinical microbiology studies. Supports investigation of microbial phosphate metabolism, particularly in wastewater treatment systems where polyphosphate-accumulating organisms play a role in nutrient removal. Also applied in studies of bacterial stress response, biofilm formation, and cellular energy regulation. The kit provides a reliable, sensitive method for high-throughput analysis in enzyme kinetics and inhibition assays.
