Fig. 1From: Neutralizing GM-CSF autoantibodies in pulmonary alveolar proteinosis, cryptococcal meningitis and severe nocardiosisRelative amounts of anti-GM-CSF antibodies. The relative amounts of antibodies were determined using a particle-based approach with GM-CSF coupled fluorescent magnetic beads (15), using a mouse monoclonal anti-GM-CSF as standard. Results for groups of patients with distinct phenotypes are expressed as mean ± SD in an arbitrary Mouse Monoclonal Antibody Unit (MMAU). Comparisons between groups were done using unpaired Student’s t-testBack to article page
