Characterization of HCT116‐E2 human colorectal cancer cells. (a) HCT116 cells were transfected with E2‐Crimson. E2‐crimson‐positive HCT116 cells were gated and sorted, and gated cells were collected. Collected cells were cultured, and this procedure was repeated twice. (b) Reflectance images of normal HCT116 cells (lower panels) and E2‐Crimson‐positive cells (upper panels) which have red excitation light.
