Used in research settings to quantify heparin binding protein (HBP), also known as azurocidin, in human biological samples such as plasma or serum. This kit is primarily applied in studies related to inflammation, sepsis, and endothelial dysfunction, as HBP is released from activated neutrophils and plays a role in vascular permeability and immune response. It enables early detection of bacterial infections and assessment of disease severity in critical care research. The assay supports investigation into biomarkers for septic shock, acute infections, and inflammatory diseases by providing a sensitive and specific measurement of HBP levels.
