Title (EN) MEMBRANE ASSEMBLY AND A LATERAL FLOW IMMUNOASSAY DEVICE COMPRISING SUCH MEMBRANE ASSEMBLY
(FR) ENSEMBLE À MEMBRANE ET DISPOSITIF D'IMMUNO-ESSAI COMPRENANT CET ENSEMBLE À MEMBRANE
Abstract:
(EN) The invention relates to an elongate membrane assembly having a length, a width and a height, the assembly comprising a microporous membrane layer supported on a liquid-impermeable support layer and the assembly being suitable for lateral flow of a liquid through the membrane layer under the action of capillary forces, wherein the assembly has a constant height and at least part of the membrane layer has a first thickness in the range of from 20 to 80 µm over the entire width of the assembly. The invention further relates to a lateral flow immunoassay device comprising such membrane assembly.
(FR) La présente invention concerne un ensemble à membrane allongé présentant une certaine longueur, une certaine largeur et une certaine hauteur, l'ensemble comprenant une couche de membrane microporeuse disposée sur une couche de support imperméable aux liquides, l'ensemble permettant un écoulement latéral d'un liquide à travers la couche de membrane sous l'effet de forces capillaires, l'ensemble ayant une hauteur constante et au moins une partie de la membrane ayant une première épaisseur se situant dans la gamme de 20 à 80 μm sur la totalité de la largeur de l'ensemble. L'invention concerne en outre un dispositif d'immuno-essai à écoulement latéral comprenant cet ensemble à membrane.
