Used to quantitatively measure total immunoglobulin G (IgG) levels in mouse biological samples such as serum, plasma, or cell culture supernatants. This kit is commonly applied in immunological research to assess humoral immune responses in mouse models. It helps evaluate immune system activation or suppression in studies related to infection, vaccination, autoimmunity, and inflammation. Due to its specificity for total mouse IgG, it does not distinguish between subclasses but provides a reliable overall IgG concentration, making it suitable for screening and monitoring antibody production in preclinical studies.
