Design of the CT26-hEpCAM-LZ cell line

The CT26-hEpCAM-LZ clonal cell line expresses high levels of human EpCAM, and forms solid tumors in vivo. An optimized version of a luciferase-ZsGreen (LZ) fusion protein is also stably expressed for in vivo imaging and ex vivo tracking.

CT26-hEpCAM-LZ features

  • Express a fully human EpCAM
  • Express a luciferase-ZsGreen (LZ) fusion reporter
  • Form solid tumors upon subcutaneous injection in fully immunocompetent mice
  • Injected cells can be followed in vivo and ex vivo with our LZ reporter
  • CT26-hEpCAM-LZ cells homogeneously express human EpCAM in vitro

    Expression analysis by flow cytometry. Human EpCAM expression assessed in CT26.WT parental cell line (left), human control cell line (center), and CT26-hEpCAM cell line (right).

     
  • CT26-hEpCAM-LZ cells form tumors in vivo

    Wild-type Balb/c mice were injected (s.c.) with 1x106 CT26-LZ (left) or CT26-hEpCAM-LZ (right) cells. Tumor growth was measured every 2 to 3 days. Tumor size (mm3) = (width2 x length)/2.
