Used in research settings to quantify Clara cell secretory protein (CC16) levels in biological samples such as serum, plasma, bronchoalveolar lavage fluid, and urine. This assay is particularly valuable in studies related to lung injury, inflammation, and respiratory diseases including asthma, chronic obstructive pulmonary disease (COPD), and acute respiratory distress syndrome (ARDS). Due to the sensitivity and specificity of ELISA, this kit enables researchers to assess epithelial damage in the airways, monitor disease progression, and evaluate the effectiveness of therapeutic interventions. It is also employed in environmental and occupational health studies to detect early signs of lung toxicity caused by pollutants, smoking, or chemical exposure.
