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 immune response to 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 diagnostic method development. The kit provides a reliable, high-throughput method for measuring antibody levels, supporting investigation into infection prevalence, treatment efficacy, and host immune responses. Not intended for diagnostic use in clinical practice.
