(EN) Serum- or plasma-separating composition, blood-test container, and method of stabilizing serum- or plasma-separating composition
要約
(EN)

There is provided a serum- or plasma-separating composition less likely to cause separation between a liquid organic compound and a thixotropy imparting component and capable of maintaining a homogeneous blended state for a prolonged period. The serum- or plasma-separating composition comprises a liquid organic compound, a thixotropy imparting component, and a thermoplastic elastomer.
