Used in immunological research to quantitatively measure soluble CD14 levels in biological samples such as serum, plasma, and cell culture supernatants. This kit is particularly valuable in studies related to innate immunity, inflammation, and monocyte/macrophage activation. It helps investigate conditions like sepsis, infectious diseases, and chronic inflammatory disorders by providing a reliable method to monitor CD14 expression, which serves as a co-receptor for bacterial lipopolysaccharide (LPS) and plays a key role in the immune response to gram-negative infections. Widely applied in preclinical research and biomarker validation in mouse models.
