Title:
CELL SEGREGATING AGENT, PRODUCTION THEREOF, CELL SEGREGATING DEVICE USING SAID AGENT AND METHOD FOR REMOVING IMMUNOSUPPRESSIVE LYMPHOCYTE AND/OR IMMUNOSUPPRESSIVE FACTOR FORMING CELL USING SAID AGENT
Document Type and Number:
Japanese Patent JPS63284
Kind Code:
A
Abstract:

PURPOSE: A cell segregating agent capable of adsorbing a desired cell such as immunosuppressive lymphocyte or immunosuppressive factor forming cell from a flotation solution of animal cell group and separating, comprising fibers of hydroxyapatite.

CONSTITUTION: Hydroxyapatite is dispersed into an aqueous solution of a water- soluble high polymer compound and the dispersion is extruded from a nozzle 5 to form a fiber flow. A high-speed gas flow is jetted to the fiber flow, the fiber flow is heated to ≥100°C and water content is removed to give fibers. Then, the fibers are sintered at 200W1,350°C. The fibers 22 have preferably 1W100μm average diameter. The hydroxyapatite is preferably hydroxy calcium apatite and has especially preferably a ratio Ca/P of calcium Ca to phosphorus P of 1.4W1.8.
