Used in biomedical research to measure levels of protease-activated receptor 1 (PAR1) in rat samples, this ELISA kit enables scientists to study the role of PAR1 in physiological and pathological processes. It is particularly valuable in cardiovascular research, as PAR1 is involved in platelet activation, thrombosis, and vascular inflammation. Researchers use the kit to evaluate PAR1 expression in experimental models of stroke, myocardial infarction, and atherosclerosis. It also supports studies in cancer and neurodegenerative diseases where protease signaling pathways contribute to disease progression. The assay provides a quantitative and sensitive method to monitor changes in PAR1 levels in response to drug treatments or genetic modifications.
