Integral multilayer analytical element |
摘要 |
An integral multilayer analytical element which comprises a water-impermeable light-transmissive support, a hydrophilic layer containing a water-absorptive hydrophilic polymer binder and a spreading layer superposed in this order, and contains at least one reagent capable of reacting with a component of a sample to produce a detectable species capable of detecting by light, which is characterized in that light-scattering particulates in an amount to make light transmittance to 10 to 2.5% are contained in the above hydrophilic layer and/or a layer located on the side of the support therefrom. This element may decrease the influence of a conventional reagent layer up to the extent being negligible without lowering the sensitivity. Precision of the measurement at a low concentration range is also high, and reproducibility of the meaurement is well. Manufacture of this element is easy.
