  • Devices and methods for detecting and sorting biological particles in a liquid flow using substantially uniform intensity along a direction of flow of a flow cell
    Patent number: 8767212
    Abstract: In at least one embodiment, a flow cytometer includes a flow cell defining a sheath flow encompassing a dyed biological particle, a first optical source irradiating first light onto the flow cell, a second optical source irradiating second light onto the flow cell downstream where the first light is irradiated, a first optical detector detecting scattered light or fluorescence from the biological particle to output a first electrical signal corresponding thereto, a plurality of second optical detectors arranged along the flow cell, each of the second optical detectors detecting fluorescence from the biological particle to output a second electrical signal corresponding thereto, and a signal processor summing the second electrical signals output from the plurality of the second optical detectors in a plurality of time windows estimated based upon when the first optical detector detects the scattered light or the fluorescence, thereby to increase the second electrical signals of the fluorescence from the biolog

  • ANTI-lgSF4 ANTIBODY AND UTILIZATION OF THE SAME
    Publication number: 20120046451
    Abstract: It is intended to clarify a molecule which is available as a target in treating or diagnosing cancer and utilize the molecule in the medical field or the research field. By treating IgSF4, which has been identified as a molecule specifically expressed in lung cancer cells, with an antibody, and ADCC activity is exerted. Based on this finding, an anti-IgSF4 antibody is provided as a means efficacious in treating cancer, etc.
