Cell Associated A1PI Detection in Human Lung Tissue.

<p>Lung tissue acquired at autopsy from patients with advanced lung disease associated with cystic fibrosis (n = 8, top row) and acute fatal respiratory syncytial virus infection (n = 9, bottom row). Representative detection of macrophage antigen CD68 (left panels), A1PI (middle panels), or irrelevant species-matched control antibody (right panels) are shown. Bar = 30 µm top row, 15 µm bottom row.
