Used in immunological research to detect and quantify pig IgG2 antibodies in biological samples such as serum, plasma, or cell culture supernatants. Commonly applied in veterinary studies, vaccine development, and infectious disease monitoring in swine. Helps assess immune responses in pig models, particularly in research involving pathogens like porcine reproductive and respiratory syndrome virus (PRRSV), influenza, or bacterial infections. Suitable for high-throughput screening in diagnostic laboratories and preclinical trials.
