Surface proteins of two aflatoxin producing isolates of aspergillus flavus and aspergillus parasiticus mycelia 1. a comparative immunochemical profile



Surface proteins of two aflatoxin producing isolates of aspergillus flavus and aspergillus parasiticus mycelia 1. a comparative immunochemical profile



Journal of Agricultural and Food Chemistry 40(9): 1610-1612



The surface antigens from Aspergillus flavus and Aspergillus parasiticus mycelia were characterized by immunochemical analysis on agarose gels. Results of immunoabsorption experiments showed that at least two antigens present in A. flavus were not detected in A. parasiticus. Semiquantitative and qualitative assays by line and crssed immunoelectrophoresis showed extreme heterogeneity in precipitin formation between the two fungi. A major antigen in A. parasiticus appeared in trace amounts in A. flavus; that antigen might be useful as a chemical marker in species identification studies. The avidity of antibody responses varied between the two isolates but the homology of the profiles support their close phylogenetic relationship as members of the same genus.
