Used in biomedical research to quantify TIEG1 protein levels in rat tissue extracts or biological fluids. Helps investigate the role of TIEG1 in cellular processes such as apoptosis, cell differentiation, and response to TGF-β signaling. Commonly applied in studies related to bone metabolism, pancreatic function, and fibrosis. Enables researchers to assess changes in TIEG1 expression under experimental conditions, supporting mechanistic insights in disease models and drug development.
