Used in immunological research to quantify levels of intercellular adhesion molecule-1 (ICAM-1) in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is specifically designed for detecting rat ICAM-1, making it a valuable tool in studies related to inflammation, immune response, and endothelial activation. It is commonly applied in research on diseases involving vascular inflammation, such as arthritis, asthma, ischemia-reperfusion injury, and neuroinflammatory conditions. The assay enables researchers to monitor changes in ICAM-1 expression under experimental treatments, assess the efficacy of anti-inflammatory compounds, and investigate mechanisms of leukocyte migration and cell signaling in rat models.
