title: Antibody determination against Aspergillus fumigatus by means of the enzyme-linked immunosorbent assay. I. Liberation of polystyrene binding components during cultivation.
abstract: The liberation of polystyrene binding antigenic components (PBC) of Aspergillus fumigatus involved in ELISA IgG measurements was studied during cultivation in the culture filtrates. PBC were rapidly liberated into the culture medium during the logarithmic phase of growth (phase I), were in part degraded or reconsumed during the stationary phase (phase II) and again secreted (other PBC) during the lytic phase (phase III). ELISA IgG titers and numbers of precipitating components are not always related with one another, may show an inverse relationship; maximal ELISA titers are reached during phase I when precipitating components are limited. The striking similarity between the liberation of PBC and IgE-binding components is discussed.
