Abstract
The present invention provides a process of quantifying the number of viable cells in an aqueous suspension of cells using an energy-emitting non-hazardous probe and a probe-trigger. The process provides quantification data in short periods of time without the use of hazardous materials. A process of the present invention can also be used to quantify negatively charged particle number, assay for cytotoxicity, assay for cell proliferation and assay for cell differentiation. Still further, the present invention provides an assay kit for quantification of cells or negatively charged particles.
