  • Publication number: 20120015429
    Abstract: The present invention relates to a lateral flow assay and system, including a test strip, for detection and quantification of analytes in samples, such as samples containing cells and fluid. In general, according to the present invention, a test strip for a lateral flow assay for detection of at least one analyte in a sample comprises: (1) a chromatographic strip, a sample filter, a fluid-impermeable barrier, and means for providing a mobilizable detectable agent that is capable of binding to the at least one analyte or to the capture agent after capturing the analyte to the chromatographic strip such that the mobilizable detectable agent migrates through the chromatographic strip and contacts sample that has passed through the sample filter and also has migrated through the chromatographic strip. The test strip allows detection with or without quantitation of an analyte in a sample containing whole cells.

  • Publication number: 20100099112
    Abstract: The present invention relates to a lateral flow assay and system, including a test strip, for detection and quantification of analytes in samples, such as samples containing cells and fluid, where the assay is volume independent, and the sample size is less than about 100 ?l, where the test strip includes a first membrane such as a sample filter, that is in capillary contact with an optional second membrane, such as a fluid collector, the second membrane, if present is in capillary contact with an optional third membrane, such as a conjugate pad containing a mobilizable detectable agent, or with a fourth membrane, which is a chromatographic strip, which optionally contains a mobilizable detectable agent, all such membranes being in fluid contact with a fifth membrane, such as a buffer pad, a sixth membrane, such as an absorbent pad, optionally a seventh membrane, which is also an absorbent pad, a capture band for capturing the analyte and at least one control band, or alternatively, the chromatographic strip
