Used in research settings to detect and quantify IgG antibodies against Helicobacter pylori in human serum or plasma samples. This ELISA kit enables scientists to assess past or chronic H. pylori infection, which is associated with gastritis, peptic ulcers, and increased risk of gastric cancer. It is commonly applied in clinical studies, epidemiological surveys, and immune response investigations. The assay supports high-throughput screening and provides a reliable, sensitive method for measuring antibody levels, aiding in the evaluation of infection status and immune activity in patient populations.
