摘要：
A method of preparing a dry-type analytical element for immunoassay having at least one water-permeable porous layer and containing a labeled antigen and an antibody to said labeled antigen and to an unlabeled antigen as the components participating in antigen-antibody reaction in said porous layer, which comprises applying or impregnating a first composition containing one of said labeled antigen and said antibody and thereafter applying or impregnating a second composition containing the other of said labeled antigen and said antibody dissolved or suspended in a solvent not dissolving substantially said labeled antigen or said antibody in the first composition onto said porous layer.
