PURPOSE:To accelerate blood clotting and to improve sepn. of a blood-clot and serum and the yield of the serum by adding borate of specific bivalent or higher valency metallic ion to a blood and subjecting the blood to a centrifugal sepn. CONSTITUTION:Borate of vibalent or higher valency metallic ion selected from the group of Cu<2+>, Co<2+>, Fe<2+>, Ni<2+>, Mg<2+> and Ce<3+> as a blood clotting accelerator is added to a blood at <=1X10<-10>-10<-1>g for each 1ml the blood to clot the blood, then the blood is subjected to a centrifugal sepn. The clotting is completed within 30- 60min by using either glass or PE spitz for the blood vessel and the shrink characteristic of the blood-clot is good. The serum contg. no blood clot component is obtd. with a good yield by the centrifugal sepn. If said borate is added in the form of powder or concd. soln., there is the possibility of causing a deterioration in the properties of the protein component in the blood and if the soln. is too thin, the serum is diluted, thus hindering the inspection of the serum. It is therefore a good practice to disperse the borate deposited on a suitable carrier into 1.0wt% physiological salt soln. and adding such soln. to the blood. |
