ABSTRACT:
A serum:plasma separator is provided containing a tackifier having a softening point of 70.degree. to 150.degree. C. and a partition-forming material. The separator prevents hemocyte from remaining in a serum portion after blood separation and prevents migration of a component having a concentration gradient between clot and serum, even when separated blood components are stored as they are in place in a tube for the separation of blood, whereby correct examination results can be obtained. The serum:plasma separator hardly undergoes a form change at room temperature and under heat and hardly shows a viscosity change even after a long period of time. Further, the serum:plasma separator has an excellent thixotropic nature free from a change in temperature, excellent cohesion and excellent adhesion to a blood separation tube. There is also provided a tube for the separation of serum:plasma from clot;hemocyte, which contains the above serum:plasma separator.
