Used to quantitatively measure total immunoglobulin G (IgG) levels in mouse biological samples such as serum, plasma, or cell culture supernatants. This high-sensitivity kit is ideal for monitoring immune responses in preclinical research, including studies on vaccine development, infectious diseases, autoimmune disorders, and immunotherapy. The assay enables accurate detection of low-abundance IgG, making it suitable for longitudinal studies where small sample volumes or early immune changes must be detected. It is widely used in biomedical research and pharmaceutical testing involving mouse models.
