Used in research settings to quantify soluble urokinase plasminogen activator receptor (suPAR) levels in biological samples such as serum, plasma, and urine. Elevated suPAR levels are associated with immune activation and inflammation, making this kit valuable in studies related to chronic kidney disease, cardiovascular diseases, cancer progression, and infectious diseases like HIV and sepsis. It supports biomarker validation and clinical research aimed at understanding disease prognosis and immune system involvement. The assay is not for diagnostic use but serves as a tool for investigative and translational research in immunology and molecular medicine.
