Used in biomedical research to measure soluble urokinase-type plasminogen activator receptor (suPAR) levels in rat biological samples such as serum, plasma, or tissue homogenates. The kit enables quantification of suPAR, a biomarker associated with immune activation, inflammation, and disease progression. It is widely applied in studies related to kidney disease, cancer, metabolic disorders, and infectious diseases in rat models. The ELISA format allows for high sensitivity and specificity, making it suitable for monitoring disease states and evaluating therapeutic interventions in preclinical research.
