Used in biomedical research to detect and quantify VacA toxin levels in biological samples. Commonly applied in studies related to Helicobacter pylori infections, allowing researchers to assess toxin production and secretion in vitro. Widely used in immunology and gastroenterology research to investigate host-pathogen interactions, evaluate vaccine efficacy, and measure immune responses. Suitable for serum, plasma, and cell culture supernatant analysis. Supports high-throughput screening in clinical and laboratory settings.
