Abstract

A highly sensitive microfluidic device has been developed to separate apoptotic cells. Apoptotic Jurkat cells were selectively labeled with magnetic beads (0.8 μm diam) using the C2A protein which recognizes phosphatidylserine. The cell mixture was flowed through a microfluidic channel and apoptotic cells were separated by a 0.3 T permanent magnet. Separations using our device showed 96% agreement with those of a commercial flow cytometer, indicating our device can be used to sort apoptotic cells in a miniaturized system.
