Protocol
anti-EA (D) EBV IgA assay i s a solid-phase immunoanalytical test. The polystyrene strips are coated with a recombinant antigen that b ears immunodominant epitopes of EA protein. The anti- EA (D) antibodies, if present in the serum, bind t o the immobilized antigens. The antibodies that do not bind are washed away and those that formed compl exes with the antigens are later on recognised by animal anti-human IgA antibodies labelled with horserad ish peroxidase. The presence of labelled antibodies is revealed by an enzymatic reaction with a chromogenic substrate. Negative sera do not react and the mild change in colour, if present, may be attributed to the reaction background
