Figure 1

Describes the percent of immunologically recognized epitopes remaining in a solution of A. alternata antigen material after treatment with increasingly dilute concentrations of sodium hypochlorite. Three different assay methods are depicted including an inhibition immunoassay for total antigen epitopes, direct immunoassay for total epitopes, and direct immunoassay for allergenic epitopes. The figure indicates nearly all epitopes are destroyed by hypochlorite concentrations of 38 mM or greater.
