Open the CIPO recordAbstract From the Canadian patent
A hybrid cell line capable of producing monoclonal antibodies uniquely specific to human neutrophils. The monoclonal antibody has no reactivity with other human peripheral blood cells and virtually no reactivity with granulocyte precursors or other cells in bone marrow. Further there is no reactivity with human acute leukemia cells. One of the partners in the hybridoma fusion of a mouse spleen cell developed from using highly purified human granulocytes as the immunization agent. The monoclonal antibody further is characterized by its capability of being used to enumerate and isolate neutrophils in normal peripheral blood and patients with acute leukemia.
