Used in immunological research to detect and quantify mouse mucin 1 (MUC-1) protein levels in biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. Commonly applied in studies related to inflammation, autoimmune diseases, and cancer, particularly in mouse models where MUC-1 serves as a biomarker for tumor progression and immune response modulation. The ELISA format allows for high sensitivity and specificity, enabling researchers to monitor changes in MUC-1 expression under experimental conditions, assess therapeutic efficacy, or investigate mucosal immunity mechanisms.
