Used in immunological research to quantitatively measure mouse Complement 1q (C1q) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly useful in studies related to the innate immune system, autoimmune diseases, and inflammation, where C1q plays a key role in activating the classical complement pathway. It enables researchers to assess C1q expression in mouse models of disease, including lupus, neurodegenerative disorders, and infections, supporting the evaluation of immune responses and therapeutic interventions. The assay provides high specificity and sensitivity, making it suitable for detecting subtle changes in C1q concentration during experimental treatments.
