  • Patent number: 11860157
    Abstract: A microfilter having a hydrophilic surface and suited for size-based capture and analysis of cells, such as circulating cancer cells, from whole blood and other human fluids is disclosed. The filter material is photo-definable, allowing the formation of precision pores by UV lithography. Exemplary embodiments provide a device that combines a microfilter with 3D nanotopography in culture scaffolds that mimic the 3D in vivo environment to better facilitate growth of captured cells.

  • Publication number: 20140302526
    Abstract: Detection of ZAP-70 expression provides important information about disease progression and overall survival in patients with chronic lymphocytic leukemia (CLL). The invention provides methods for diagnosing CLL in a subject, as well as methods for clearly distinguishing CLL patients with aggressive form of the disease. A consistent number of B cells from patient blood is isolated and lysed to release all of the intracellular ZAP-70 protein. The released ZAP-70 protein is subsequently extracted by immunomagnetic separation followed by detection with fluorescence immunosandwich assay. The ZAP-70 fluorescence signal is measured with Signalyte™-II spectrofluorometer. The VeriZAP™ assay is a simple, reliable, and reproducible method for quantitative detection of ZAP-70 in patient leukemic cells, and can be used as a prognostic test to distinguish indolent versus aggressive CLL patients.

  • Publication number: 20100279322
    Abstract: A method of detecting target cells and pathogens in a test sample concentrates to target cells in solution by filtering or capturing the target cells on a solid support. The target cells are tagged with a fluorescent dye and dispersed in a solution or suspension. The resulting solution or suspension are introduced to a fluorometer to specifically identify and quantitate the target cells. The target cells can be lysed or whole when introduced to the fluorometer.
