Used in biomedical research to quantitatively measure Pleiotrophin (PTN), a protein involved in cell growth, differentiation, and tissue development. The kit enables researchers to detect PTN levels in biological samples such as serum, plasma, and cell culture supernatants. It is widely applied in studies related to cancer progression, neurodevelopment, angiogenesis, and bone formation. Due to PTN's role in tumor growth and metastasis, this ELISA kit supports oncology research by helping evaluate PTN as a potential biomarker. It is also used in neuroscience to investigate neural repair mechanisms and in regenerative medicine to monitor growth factor activity during tissue engineering. The assay provides high sensitivity and specificity, making it suitable for preclinical studies and diagnostic development.
