A. Levels of anti-transducin-α peptide autoantibodies in AR patients (n=39) and control subjects without visual problems (n=18), patients with uveitis (n=12) and age related macular degeneration (ARMD, n=10) measured by ELISA were significantly different among the groups (Man Whitney test, p<0.001) with the control group having the smallest median deviation (A). One ELISA unit is defined as A405 = 0.1. B: Inhibition of binding to transducin-α peptide by anti-transducin-α antibodies from 5 representative patients, as measured by the inhibition ELISA test. Numbers on the left site of the graph indicate the patient's number as in Table 1. For both tests 0.1 μg of peptide, containing amino acid rod transducin-α sequence 17-30, was coated on the ELISA plate.
