Figure 2

Comparison of cell capture with and without the capture antibody coating. A) The first vertical interface without anti-CD71 coating after 60 minutes of flowing HuT 78 cells (CD71+) through the device. Low non-specific capture was observed at all vertical interfaces. B) The first vertical interface with anti-CD71 capture antibodies. HuT 78 cells were observed to collect at the channel interfaces, indicating antibody capture was the primary mechanism of cell separation. Scale bar represents 100 μm.
