    摘要: The invention concerns a method for the determination of antigen-specific antibodies of the immunoglobulin M class in the presence of immunoglobulins of the G class and/or rheumatoid factors in body fluids by incubation with at least two different receptors R1 and R2 and optionally additional receptors wherein an essential component of R2 is a binding partner in a polymeric form and interference by IgG antibodies of the same antigen specificity is reduced by binding partners in a monomeric form; a reagent for determining an antigen-specific antibody of the immunoglobulin M class, as well as the use of binding partners in a monomeric form to reduce interference by IgG antibodies in the determination of antigen-specific IgM antibodies.

    摘要: The present invention provides a process for the detection of analytes in body fluids containing free biotin by immunoassay with the use of biotin conjugates for the labelling, immobilization or complexing of immunological reagents, wherein the biotin present in free form is removed from the immunological reaction by incubating the sample solution with polymer particles consisting of a core and a covering which, as core, contain a polymer which has a plurality of binding sites for biotin and, as covering, at least one layer of protein, peptide, carbohydrate or co-polymer of carbohydrate and amino acids, the layer thickness of the covering being so adjusted that the coating is permeable for the free biotin but not for the biotin conjugate.
