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 invention concerns the use of peptides which are comprised essentially of D-amino acids to eliminate interference in diagnostic methods, a method for eliminating interference in diagnostic methods by peptides which are comprised essentially of D-amino acids as well as a reagent that eliminates interference containing at least one peptide which is comprised essentially of D-amino acids.
摘要:
The present invention concerns a method for the determination of an analyte in a sample liquid using a metal complex capable of luminescence as an analyte-specific marker group for the production of a measuring signal in which an unspecific metal complex is additionally added as an interference elimination reagent which has a structure that is chemically related to the marker group.
摘要:
The invention concerns a method for the immunological determination of a specific antibody in a sample liquid in which the sample liquid is incubated in the presence of a solid phase with two antigens directed against the antibody to be determined of which the first antigen carries at least one marker group and the second antigen is (a) bound to the solid phase or (b) is present in a form capable of binding to the solid phase and the antibody to be determined is detected by determining the marker group in the solid phase or/and in the liquid phase characterized in that at least one of the two antigens contains several epitope regions which react with the antibody to be determined.
摘要:
The present invention concerns an antibody against a hepatitis G virus antigen as well as a fragment of this antibody. The invention additionally concerns hybridoma cell lines as well as a conjugate that contains this antibody or the antibody fragment coupled to a biological molecule. Finally the present invention concerns the use of the antibody for the diagnostic detection of hepatitis G virus.
摘要:
The present invention concerns an improved method for the determination of fibrin in body fluids in which before the actual determination the sample solution containing fibrin is incubated in the presence of thiocyanate, iodide, magnesium or/and guanidinium ions.
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.
