Used in immunological research to quantify soluble CD14 levels in biological samples such as serum, plasma, and cell culture supernatants. Widely applied in studies related to innate immunity, inflammation, and monocyte/macrophage activation. Helps investigate conditions like sepsis, infectious diseases, autoimmune disorders, and metabolic syndromes where CD14 plays a role in LPS-mediated signaling. The kit enables high-throughput, sensitive, and specific detection, supporting both clinical research and drug development.
