    A microplate enzyme-immunoassay technique for the detection of specific anti-Lolium perenne IgE antibodies is described. This method consists of coating polystyrene wells with goat antihuman IgE (epsilon chain specific) and late selecting the IgE from the patients serum in order to finally reveal the bound specific IgE by means of a crude L. perenne extract conjugated with peroxidase. The optimal conditions necessary to achieve maximum sensitivity and specificity using this system have been studied. After testing 98 sera, the results showed a 97.9% correlation between our technique and the RAST.

    Enzyme-Linked Immunosorbent Assay

    In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
    There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or quantified.
