Used in biomedical research to measure levels of Tie-2 (tyrosine kinase receptor-2) in human biological samples such as serum, plasma, or cell culture supernatants. It is essential for studying angiogenesis, vascular development, and endothelial cell function. Commonly applied in research related to cancer, cardiovascular diseases, and inflammatory conditions where Tie-2 signaling plays a role. The kit enables accurate quantification of soluble Tie-2 protein, helping researchers assess biomarker levels and evaluate therapeutic responses in clinical and preclinical studies.
