Abstract
A method for preparing treated naturally occurring or synthetic particles using a blood cell processor is provided. The method comprises adjusting the blood cell processor to allow a dispersion of such particles to come into contact with a treatment material in an amount and for a period of time sufficient to modify all or a portion of the surface of such particles. In a preferred embodiment, the method comprises washing collected red blood cells; separating a selected volume of said washed red blood cells; and treating one portion of said separated washed cells with a selected proteolytic enzyme, to prepare a red blood cell reagent.
