    摘要: The present invention recognizes that diagnosis and prognosis of many conditions can depend on the enrichment of rare cells from a complex fluid sample. In particular, the enrichment of fetal cells from maternal samples, such as maternal blood samples, can greatly aid in the detection of fetal abnormalities or a variety of genetic conditions. In addition, the present invention recognizes that the enrichment of rare malignant cells from patient samples, can aid in diagnosis, prognosis, and development of therapeutic modalities for patients. The invention includes microfabricated filters for filtering fluid samples and methods of enriching rare cells of fluid samples using microfabricated filters of the present invention. The invention also includes solutions for the selective sedimentation of red blood cells (RBCs) from a blood sample and methods of using selective RBC sedimentation solutions for enriching rare cells of a fluid sample. Yet another aspect of the invention is an automated system for processing a fluid sample that includes: at least one filtration chamber that includes a microfabricated filter; automated means for directing fluid flow through at least one filtration chamber of the automated system, and means for collecting enriched rare cells. The present invention also includes methods of using automated systems for separating rare cells from fluid samples. Preferred fluid samples are blood, effusion, or urine samples, and rare cells that can be enriched from such sample include nucleated red blood cells and cancer cells.

    摘要: The present invention recognizes that the determination of ion transport function or properties using direct detection methods, such as whole cell recording or single channel recording, are preferable to methods that utilize indirect detection methods, such as FRET based detection system. The present invention provides biochips and other fluidic components and methods of use that allow for the direct analysis of ion transport function or properties using microfabricated structures that can allow for automated detection of ion transport function or properties. These biochips and fluidic components and methods of use thereof are particularly appropriate for automating the detection of ion transport function or properties, particularly for screening purposes.
