A composition and a method for using the composition for manipulating the electronic and optical properties of biological particles are disclosed. The composition generally has a hypotonic buffering solution, a polyhydroxy alcohol, a stabilizing agent, and, in some applications, a non-ionic surfactant. By varying the relative concentrations of these components and by adjusting the timing of their combination and interaction, the composition and method allow for the alteration of the electronic and optical properties of the particles to achieve target values for the properties. In one particularly advantageous application, the composition and method of the invention allow for the creation of selected analogs for the subpopulations of human leukocytes from a single biological particle for use as a control product in differentiating particle analyzers.
