Method for determining antibodies of a particular class using an immune complex-specific antibody

摘要

The invention concerns a method for determining antigen-specific antibodies of a particular immunoglobulin class in a sample by means of an immunoassay in an array format in which various binding partners B nx are bound on different discrete areas on a support where B nx in each case contain the various antigens that are able to specifically bind to the antibodies to be detected, by incubating the support with the sample and a binding partner B 2 which carries a label and subsequently detecting the label on the respective discrete areas wherein B 2 specifically binds antibodies of a certain immunoglobulin class that have been bound in an antigen-specific manner.
