An optimized bronchoalveolar lavage fluid analysis method in inhalation toxicity studies of nanomaterials

This technical specification (TS) provides an optimized BALF analysis method in inhalation toxicity studies of nanomaterials. This technical specification will include the collection and preparation method for the BALF analysis in the aspect of inflammatory cell counts and levels of lactate dehydrogenase, total protein, and inflammatory mediators. In addition, this TS includes nanomaterial-specific considerations, such as inflammation patterns, proposed inflammatory mediators, and interferences in measurements. This TS is optimized for half-lung lavage of Sprague-Dawley (SD) rats but also provides information for the lavage volume of different strains and volume-determining parameters.
