<p>Disclosed are: a porous solid phase for use in a binding assay method, which enables the analysis of a sample of interest (e.g., whole blood) rapidly, conveniently, accurately and at low cost without the need of any specific pretreatment procedure after the collection of the sample; and a binding assay method using the porous solid phase. Specifically disclosed are: a porous solid phase for use in a binding assay, which is characterized in that at least one surfactant selected from the group consisting of the following surfactants (A) to (C) is added to the porous solid phase before a sample to be measured is added to the porous solid phase: (A) a sugar-containing surfactant comprising a compound represented by general formula (I), (B) a sugar-containing surfactant comprising a sucrose fatty acid ester in which a fatty acid component has 5 to 14 carbon atoms, and (C) a steroid-type surfactant; and a binding assay method using the porous solid phase.</p> |
