Used in biomedical research to quantitatively measure Smad7 protein levels in cell lysates, tissue extracts, and biological fluids such as serum or plasma. Widely applied in studies related to TGF-β signaling pathways, which play key roles in cell growth, differentiation, immune regulation, and apoptosis. Particularly valuable in inflammation and cancer research, where dysregulation of Smad7 affects disease progression. Enables researchers to assess the impact of therapeutic agents on Smad7 expression in experimental models. Commonly used in preclinical studies to evaluate drug efficacy and in biomarker discovery for autoimmune diseases, fibrosis, and malignancies.
