Used in biomedical research to quantify angiopoietin receptor Tie1 levels in biological samples such as serum, plasma, and cell culture supernatants. Enables researchers to study the role of Tie1 in angiogenesis, vascular development, and endothelial cell function. Commonly applied in studies related to cancer, cardiovascular diseases, and inflammatory conditions where vascular remodeling plays a critical role. Provides a reliable, sensitive, and high-throughput method for detecting Tie1 protein, supporting both basic research and biomarker validation in clinical investigations.
