Title: MEMBRANE ASSEMBLY AND A LATERAL FLOW IMMUNOASSAY DEVICE COMPRISING SUCH MEMBRANE ASSEMBLY
Abstract:
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.
