  • Method and device for the determination of minor cell population in heterogeneous cell populations
    Patent number: 8841082
    Abstract: The invention relates to a method for determining one or more cellularly bound analytes in a liquid sample, said method being carried out using a device comprising: at least one feeding zone (5) for applying the liquid sample; a porous membrane (2) that is suitable for letting cellular components penetrate therethrough and includes at least one indicator zone on the membrane, said indicator zone being able to interact with the cellularly bound analyte and containing at least one binding element against the cellularly bound analyte; and at least one absorption area (3) on the membrane, which absorbs the liquid after the liquid has passed the indicator zones. The at least one indicator zone lies between the feeding zone (5) and the absorption area (3).
