  • Panel cell used for granulocyte antibody detection
    Patent number: 8008028
    Abstract: A panel cell for detecting anti-HNA antibody is disclosed. The panel cell is obtained by introducing a DNA coding for an HNA antigen corresponding to the anti-HNA antibody into a cell so as to enable the expression of the DNA under the condition for use in the detection procedure, wherein the cell for DNA introduction exhibits no detectable reaction with anti-HLA-ABC antibody, anti-HLA-DR antibody, anti-HLA-DQ antibody, anti-HLA-DP antibody, anti-HNA-1 antibody, anti-HNA-2a antibody, anti-HNA-3a antibody, anti-HNA-4 antibody, anti-HNA-5 antibody, and serum from normal subject, in the detection procedure. The panel cell allows accurate and rapid detection of granulocyte antibody.
