Abstract (en)

[origin: WO9964863A1] The present invention discloses a simplified, sensitive and specific immunoassay test procedure for the determination and detection of an immunologically reactive analyte in aqueous sample. A capture membrane comprising a dendrimer which aligns a capture antibody on a solid surface so that the capture capability of the capture antibody is optimized, resulting in a minimum loss in binding activity between the capture antibody and the ligand.
