Analysis Note
Protein determined by biuret.
Biochem/physiol Actions
Pepsinogen is the zymogen of pepsin. It is processed by autocatalytic cleavage of 44 amino acids to generate active pepsin. Serum levels of pepsinogen have been measured to identify gastric cancer risk.
Other Notes
One unit will produce a ΔA280 of 0.001 per min at pH 2.0 at 37 °C, measured as TCA-soluble products, using hemoglobin as substrate. (Final volume = 16 mL. Light path = 1 cm.)

Pepsinogen (PG) method is widely used to identify high risk groups of gastric cancer. It is very useful before Helicobacter pylori eradication, but after eradication the method becomes useless because the PGI, PGII, PGI/II ratios change. Therefore, we aimed to
