  • Method for antigen and antibody determination in bloodgroup serology
    Patent number: 6303390
    Abstract: Method and test kit for assaying in a sample an analyte which is a bloodgroup antigen present on erythrocytes or an antibody binding to such a bloodgroup antigen. To that end, the sample is treated with a reagent containing a binding partner for the analyte, so that a complex of bloodgroup antigen present on erythrocytes and antibody bound thereto is formed if the sample contains analyte. The analyte is a bloodgroup antigen present on erythrocytes, the analyte binding partner is an antibody capable of binding to the bloodgroup antigen and if the analyte is an antibody binding to a bloodgroup antigen, the analyte binding partner is the bloodgroup antigen present on erythrocytes. Erythrocytes, complex or non-complexed, are then separated from non-bound antibodies using a separation medium with a density higher than that of the liquid containing the antibodies but lower than the density of crythrocytes.
