Quantitation of SerpinB1 in cystic fibrosis (CF) bronchoalveolar lavage fluid (BALF). SerpinB1 (42 kDa) was quantified by immunoblot (Laemmli gels; reducing conditions) and densitometry relative to a recombinant SerpinB1 standard (Std). Data for non CF control patients, culture negative (culture−) CF patients and culture positive (culture+; >300 organisms·mL−1) CF patients are shown. Each symbol represents the mean of triplicate assays for an individual patient. NE−: neutrophil elastase-negative specimens; NE+: neutrophil elastaste positive specimens. A subset of the findings were reported in abstract form previously [22]. #: culture+ non CF control patients.
