Abstract

See full text

Contemplated whole blood separators tubes include a curable composition with a density intermediate to the density of serum and the cell-containing fraction. After centrifugation, the curable composition is located between the serum and the cell-containing fraction and preferably irradiated with UV light to initiate a curing reaction in which the curable composition solidifies to a barrier that is immobilized and resistant to breakdown at freezing temperatures and extended storage.
