Fig. 1

Immunoblotting of pigeon serum (a), pigeon intestine homogenates (b, odd number), and pigeon dropping extract (PDE) (b, even number) with serum samples from patients with bird-related hypersensitivity pneumonitis (BRHP) (a; lanes 1–8, b; lanes 1–16), patients with other hypersensitivity pneumonitis (HP) (a; lanes 9–12, b; lanes 17–24), and healthy volunteers (HV) (a; lanes 13–15, b; lanes 25–30). The arrows indicate the 26 kDa bands observed in all three sample types exposed to sera from 7 out of 8 BRHP patients (Fig. 1a, lanes 1–7, Fig. 1b lanes 1–14). The numbers indicated under each lane of Fig. 1a represent the optical density of serum IgG antibodies against recombinant IGLL-1 in BRHP patients. M, Molecular weight markers
