Used in immunological research to quantify mouse Factor B levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit is specifically designed for the detection and measurement of Factor B, a key component of the alternative complement pathway, enabling researchers to study immune system activation in mouse models. Commonly applied in studies related to inflammation, autoimmune diseases, infection responses, and complement-mediated tissue injury. The assay provides a sensitive and reliable method to assess changes in Factor B concentration under experimental conditions, supporting both basic research and preclinical evaluation of therapeutic interventions targeting the complement system.
