摘要:
An analysis material sheet is disclosed which is comprised of layers of material with strong adhesion for one another. The sheet includes a water-impermeable support having provided directly or indirectly thereon a layer of fabric. The fabric contains a hydrophobic organic polymer fiber and is physically activated on at least one surface thereof, with the physically activated surface being adhered directly or indirectly to the support. A reagent layer can be provided directly or indirectly on the liquid sample-spreading layer of fabric. By utilizing a fabric containing a hydrophobic organic polymer fiber, body fluids to be analyzed can be quickly and uniformly spread and by utilizing the physically activated surface of the fabric, strong adhesion between the layers can be obtained.

摘要:
In a method for assaying an analyte comprising applying a liquid sample containing an analyte to a spreading layer of a multilayer analysis element comprising a support having laminated thereon at least one reagent layer containing a substrate capable of converting a detectable chemical species upon reaction with the analyte and a liquid sample-spreading layer and then detecting the chemical species, a wetting liquid is applied onto the spreading layer, prior to applying the liquid sample to the spreading layer. A liquid sample having a high analyte content can be measured with high accuracy.
摘要:
A multilayer analysis sheet for analyzing liquid samples is described, comprising, in sequence, a light transmitting hydrophobic support having on one side thereof at least one layer containing at least one reagent in a binder and a liquid sample spreading layer made of fabric, which layers are laminated to form an integral unit together with the support, wherein said fabric has the ability to supply a liquid sample placed on the surface thereof to the reagent-containing layer at a substantially constant volume per unit area, which ability is conferred upon the fabric by rendering it hydrophilic; the multilayer analysis sheet can be economically manufactured without variations in quality, and improves the spreading capability of liquid samples.
