Figure 3.

HB-EGF protein concentrations in BAL from normal volunteers, patients at-risk for ARDS, and patients with established ARDS studied at sequential times. HB-EGF was quantified by human HB-EGF ELISA kit (R&D Systems) per the manufacturer’s direction. The concentration of HB-EGF (black circles) in the samples was determined by interpolation from the standard curve generated with recombinant HB-EGF. All samples were run in duplicate and repeated at least twice. Median (black bars) values are indicated.
