Used in immunological research to detect and quantify pig IgG2a antibodies in biological samples such as serum, plasma, or cell culture supernatants. This kit is particularly useful in studies involving swine immune responses, vaccine development, and infectious disease monitoring. It enables researchers to assess the presence and levels of IgG2a, which is associated with specific immune pathways, helping evaluate the effectiveness of vaccines or the progression of infections in pig models. The assay is commonly applied in veterinary research, agricultural science, and biomedical studies using swine as animal models.
