Preparation and stabilization of cells using aged transition metal solutions

摘要

The invention is directed to novel stabilized blood compositions and methods of stabilizing blood compositions for use in the quality control of analytical techniques. The novel blood compositions comprise leucocytes and an effective amount of an aged transition metal solution. The novel method comprises removing leucocytes from a blood composition to yield a depleted blood composition, stabilizing the leucocytes by treatment with an effective amount of a stabilizing agent comprising an aged transition metal solution, and then, adding the resultant stabilized leucocytes to the depleted blood composition or a second blood component composition.
