title: [Characterization of antigenic components (major and minor antigens) in an intestinal extract from pigeons].
abstract: It is generally accepted that there is a need for standardized antigens in the diagnostic of exogenous allergic alveolitis. For this reason, ten antigens in a pigeon intestinal extract were classified in major, minor and intermediate antigens according to the distribution of specific antibodies in sera of asymptomatic and ill persons by use of crossed immunoelectrophoresis. Using a reference antiserum with antibodies against all ten detected antigens it is possible to prove a reproducible antigen composition in following preparations.
