Figure 4. COM crystal-protein binding assay.

Figure 4

Purified α-enolase or carbonic anhydrase II with an equal amount (5 μg) was directly incubated with COM crystals at 4 °C overnight. After washing, COM-bound protein was detected by immunofluorescence staining. (A) An overview of the immunofluorescence staining (original magnification power = 200X). (B) Zoom-in images of the immunofluorescence stained protein (shown in red in lower panels) comparing to the bright field (upper panels) (original magnification power = 1,000X).
