Used in biomedical research to quantify Rat angiopoietin receptor Tie1 levels in biological samples such as serum, plasma, and tissue homogenates. This ELISA kit enables researchers to study the role of Tie1 in angiogenesis, vascular development, and inflammatory processes in rat models. It is particularly useful in cardiovascular research, tumor biology, and studies involving endothelial cell function. The assay provides a sensitive and specific method for monitoring changes in Tie1 expression under experimental conditions, supporting investigation into therapeutic targets for vascular-related diseases.
