Abstract
PURPOSE: To carry out the separation of serum or blood plasma at a high efficiency by subjecting collected blood to centrifugal separation in the presence of both a viscous liquid composition having a predetermined range of specific gravity, and a composition in the form of gel having no fluidity when it is in a stationary state but exhibiting thixotropy.
CONSTITUTION: Blood collected in a vessel is subjected to centrifugal separation into serum or blood plasma, and hemocytes, in the presence of (a) a viscous liquid composition, such as liquid polybutadiene, liquid polyisoprene and chlorinated polybutene, which has a specific gravity of 1.026W1.09, a fluidity when it is in a stationary state, and a viscosity of 500W2,000,000cps and (b) a composition in the form of gel, such as a composition prepared by adding silica powder to silicone fluid, which has a specific gravity smaller than that of the composition (a) and within the range of 1.026W1.09, and which has no fluidity when it is in a stationary state but exhibits thixotropy.
