  • Blood separation composition
    Patent number: 5304605
    Abstract: A blood separation composition for use in blood collection tubes. The composition comprises a fatty acid amide(s) blended with a gel-like material which is the main ingredient of said composition. The amide(s) render(s) stable and less flowable the blood separation composition during storage, allowing it to form a stable partition barrier in each collection tube when centrifuged, with the blood cells above the barrier being prevented from remaining within the serum. The blood separation composition containing the fatty acid amide(s) does not release any harmful oily substance.
