Used in biomedical research to quantify levels of Transforming Growth Factor beta 1 (TGF-β1) in biological samples such as serum, plasma, cell culture supernatants, and tissue extracts. This kit is essential for studying immune regulation, inflammation, fibrosis, cancer progression, and wound healing, as TGF-β1 plays a central role in cell growth, differentiation, and apoptosis. Researchers use it in preclinical studies to evaluate disease mechanisms and therapeutic responses, particularly in autoimmune diseases, fibrotic disorders, and tumor microenvironments. The assay provides high sensitivity and specificity, enabling accurate measurement of TGF-β1 concentration in rabbit models, which are commonly used in immunology and toxicology research.
