ENHANCED CELLULAR ASSAY METHOD FOR USE IN FLOW CYTOMETRY OR SIMILAR INSTRUMENTS USING OPTICALLY RESONANT PARTICLES

摘要

This invention relates to the field of biological assays where cells can be classified and enumerated using flow cytometry optical instrumentation. The invention combines information from multi-angle, light scatter from the cell itself and multi-angle light scatter from small, optically resonant particles that are selectively bound to surface molecules on the cell to carry out classification and enumeration. This light scatter method enables an instrumentation system that is simple to use, inexpensive to build, and mechanically robust; making it suitable for use in remote clinical environments.
