Used in research to measure levels of Clara cell protein (CC16) in biological samples such as serum, plasma, or bronchoalveolar lavage fluid. Helps assess lung epithelial damage and airway inflammation. Commonly applied in studies of respiratory diseases including asthma, COPD, cystic fibrosis, and acute lung injury. Enables evaluation of environmental or occupational exposure effects on lung health, such as in smokers or individuals exposed to pollutants or toxins. Supports biomarker validation in preclinical and clinical research settings.
