Abstract
A therapeutic product formed from a high concentration of white blood cells having a high degree of cell viability. The white blood cells are sequestered from their normal population presence in whole blood by placing the blood into a container and preventing coagulation of the blood, separating the blood into two components, one of which is extremely rich in white blood cells through the use of a reagent and centrifugation, sequestering the white cell concentration, and freezing the white cells.
