  • Patent number: 6495367
    Abstract: A blood component deposition-preventing agent and a blood coagulation accelerator are provided, which are substantially indifferent to blood coagulation activity and serum chemistry parameters. Also provided is plastic blood test ware and a blood test matrix which do not confound measured values. A blood component deposition-preventing agent comprising a random copolymer of a monomer component (a) giving a water-soluble homopolymer and a monomer component (b) giving a water-insoluble homopolymer, a blood coagulation accelerator comprising a substantially blood-insoluble antimicrobial composition comprising a carrier and, as supported thereon, an antimicrobial metal, and a blood test ware or matrix carrying them on its inside wall or surface are provided.

  • Patent number: 5510237
    Abstract: The invention provides a serum or plasma separating composition which comprises a cyclopentadiene resin, a viscosity adjusting agent and an organic gelling agent. The composition is characterized in that the cyclopentadiene resin is a liquid resin at a temperature of 25.degree. C., the viscosity adjusting agent being a liquid ester obtained from propionic acid, butyric acid, benzoic acid or phthalic acid, the organic gelling agent being a condensation product of sorbitol and an aromatic aldehyde, the composition containing 0.8 to 25 parts by weight of the viscosity adjusting agent and 0.03 to 0.9 part by weight of the organic gelling agent per 100 parts by weight of the cyclopentadiene resin. The composition forms a satisfactory separating layer even when subjected to a centrifugal separation operation at a set temperature of 4.degree. C.
