    摘要： Disclosed are devices and methods for analyzing a fluid cell containing sample. The devices are composed of a solid substrate, microfabricated to define at least one sample inlet port and a mesoscale flow system. The mesoscale flow system includes a sample flow channel, extending from the inlet port, and a cell handling region for treating cells disposed in fluid communication with the flow channel. The devices may further include a component for inducing flow of cells in the sample through the flow system. In one embodiment, the cell-handling region may include a cell lysis component to enable the lysis of cells in the sample, prior to, e.g., the detection of an intracellular component in the cell sample. In another embodiment, the cell handling region may have a cell capture region, with binding sites which reversibly bind to a specific population of cells in the cell sample, to permit the isolation of the specific cell population from the sample. The devices can be utilized in a wide range of automated sensitive and rapid tests for the analysis of a fluid cell containing sample.

    摘要： The invention discloses novel methods of detecting glycated proteins in test samples of blood and methods of detecting chronic hyperglycemia. The test sample is contacted with a binder composition under conditions which allow binding of glycated protein in the test sample to at least a portion of the binder composition. The test sample is then exposed to a glycated compound affixed to a solid support under conditions which allow raction of unbound binder composition from the previous step to at least a portion of the glycated compound on the solid support. The glycated compound affixed to a solid support from the previous step which did not react with the unbound binder composition is then reacted with a detecting agent and the detecting agent is detected.
