Final answer:
To reduce PPi concentration in blood samples, use an enzyme called pyrophosphatase (PPase) to catalyze the hydrolysis of inorganic pyrophosphate (PPi) into two phosphate ions (Pi).
Step-by-step explanation:
To reduce PPi concentration in blood samples, you can use an enzyme called pyrophosphatase (PPase). PPase catalyzes the hydrolysis of inorganic pyrophosphate (PPi) into two phosphate ions (Pi).
This reduces the concentration of PPi in the sample. PPase can be added to blood samples and incubated at the appropriate temperature and pH to facilitate the hydrolysis reaction. By using PPase, you can effectively reduce the PPi concentration in blood samples.
