System and method for high throughput cell analysis and sorting

摘要

A sorting methodology in which bulk analysis of samples that have a low probability of containing a rare particle is performed first. Only those samples in which the bulk analysis has detected one or more rare particles are subjected to a flow cytometry process to isolate the rare particle(s). In one embodiment, a microwell plate provides for high throughput sorting in an enclosed environment. The microwell plate includes a plurality of wells and a microfluidic layer adapted for flow cytometry wherein particles from a given well are interrogated and sorted into other wells. The microfluidic layer advantageously includes fluid switches to permit bi-directional flow cytometry.
