Publication number: 20140030729Abstract: An automated identification of the types of white blood cells in a blood sample facilitates the manual identification of cancerous or other abnormal blood cells in the sample. Classifiers are predetermined for each type of white blood cell and subsequently used to automatically process images of cells in a sample stained with a nuclear dye or stain. The classifiers each comprise a linear weighted combination of morphometric and photometric features previously selected for white blood cells that were identified using monoclonal antibody stains. Red blood cells and excess fluid are removed from a sample being processed upstream of an imaging region of the imaging system. A plurality of different types of images are produced for each cell by the imaging system enabling automated identification of the white blood cells. Images of any cells not thus identified are manually reviewed to detect cancerous or abnormal cells.Type: ApplicationFiled: September 27, 2013Publication date: January 30, 2014Applicant: Amnis CorporationInventors: David A.

Publication number: 20140030234Abstract: Methods and compositions are provided for modulating pancreatic islet ?-cell development. Aspects of the methods include promoting ?-cell development by providing agents that promote calcineurin/N FAT signaling, and inhibiting ?-cell development by providing agents that inhibit calcineurin/NFAT signaling. These methods find a number of uses, including, for example, in the treatment of diabetes and human islet diseases. In addition, reagents, devices and kits thereof that find use in practicing the subject methods are provided.Type: ApplicationFiled: July 11, 2013Publication date: January 30, 2014Inventors: Seung K.

Publication number: 20140030696Abstract: An apparatus for detecting an analyte in a sample includes an illumination source for generating electromagnetic energy to illuminate the sample at an interrogation region, a concave collector element having an optical axis, and a focal point, the interrogation region being coincident with the focal point of the concave collector element, a closed flow cell having a flow path defined between a sample inlet and a sample outlet, the flow path passing through the interrogation region and a sorting region disposed downstream of the interrogation region. The portion of the flow path passing through the interrogation region is coaxially aligned with the optical axis of the concave collector element. The apparatus further includes the sample comprising or suspected of comprising the analyte and flowing in the flow path, wherein the analyte generates a detectable signal in response to illumination. The apparatus also includes a detector for detecting the detectable signal.Type: ApplicationFiled: February 15, 2012Publication date: January 30, 2014Applicant: MICROBIX BIOSYSTEMS, INC.Inventors: Mark Luscher, Randall Marks
