Pepsinogen II (PGII) is applied for the screening, risk stratification, and auxiliary diagnosis of chronic atrophic gastritis, peptic ulcer diseases, and gastric cancer, as well as the dynamic monitoring of Helicobacter pylori (H. pylori) eradication therapy and gastric mucosal status.
PGII OEM kit utilizes a two-antibody sandwich immunoassay and is applicable to chemiluminescence platforms. Specific monoclonal antibodies target distinct structural epitopes on the PG II molecule to capture serum or plasma PG II, delivering high sensitivity and exceptional specificity without cross-reactivity to Pepsinogen I (PG I). Calibrated with high-purity recombinant PG II antigen, the assay provides accurate, reliable, and stable quantitative results. Serving as a key non-invasive biomarker for gastric health evaluation, when combined with PG I and the PGI/PGII ratio (PGR), it supports early identification of gastric mucosal lesions, non-invasive gastric cancer risk assessment, and clinical therapeutic efficacy monitoring.
