Used in biomedical research to quantify Smad7 protein levels in cell or tissue samples, this ELISA kit helps study the regulation of TGF-β signaling pathways. It is widely applied in investigating inflammatory diseases, fibrosis, and cancer, where Smad7 plays a key role in modulating immune responses and cellular proliferation. Researchers use it to evaluate the effectiveness of therapeutic agents targeting TGF-β pathway dysregulation. The kit enables high-sensitivity detection, supporting studies in immunology, oncology, and drug development.
