Used in biomedical research to detect and quantify CagA protein, a virulence factor produced by Helicobacter pylori. The kit enables researchers to study the presence and levels of CagA in clinical samples such as gastric tissues or serum, helping to investigate its role in gastric inflammation, peptic ulcer disease, and gastric cancer development. Widely applied in epidemiological studies to assess H. pylori strain pathogenicity and in monitoring disease progression or treatment response in infected individuals. Provides a reliable, sensitive, and high-throughput method for immunoassay-based detection in laboratory settings.
