Latest Patents
Moriyama holds a patent for a "Method for classifying leukocytes and a reagent used therefor." This invention discloses reagents that enable the classification and counting of leukocytes while lysing erythrocytes and stabilizing leukocytes. The reagents contain polyoxyethylene-based surfactants and may include hyperosmotic or hypoosmotic agents and solubilizing agents. One embodiment of the invention features surfactants selected from anionic and nonionic polyoxyethylene-based surfactants with 18-30 repeating oxyethylene units per molecule. Another embodiment consists solely of nonionic polyoxyethylene surfactants with 20-100 repeating oxyethylene units per molecule, avoiding the use of saponin or quaternary ammonium compounds, and allows for pH adjustment of the resulting solutions. This invention enables the classification of leukocytes into as many as five types, each of which can be quantified, and facilitates the detection of abnormal cells when used with particulate analysis flow cytometers employing the RF method and the DC method.
