AN INTEGRATED PACKAGING HOLDER DEVICE FOR IMMUNO-CHROMATOGRAPHIC ASSAYS IN FLOW-THROUGH OR DIPSTICK FORMATS

摘要

The present invention relates to an integrated package-holder assay device f or detecting the presence of analyte in a sample. The device serves the dual roles of supporting and protecting an immunochromatographic assay. The device is compatible with any immunochromatographic assay format. The assay can be performed in a single apparatus for use in a laboratory or a field setting. In a specific example, the assay device is a nylon membrane formatted for an immunochromatographic assay for cotinine sealed between transparent adhesive tape and a stiff plastic strip. White tape placed over the plastic strip defined a window for observing the assay results.
