hTERT Expression in Cell Lines.

<p>Top image shows hTERT expression detected at 200 bp in a Werner syndrome cell line (positive control) immortalised for hTERT (Lane1). hTERT expression is also detected in the bladder cancer cell lines RT112 and RT4 (Lanes 2 and 3 respectively). No hTERT expression was found in the normal GM38 fibroblast cell line (Lane 4) or in the two Cockayne Syndrome cell lines, CSA and CSB (Lanes 5 and 6 respectively). Bottom image shows the expression of housekeeping control gene GAPDH at 440 bp in all six cell lines (Lanes 1–6). (Lane M, 100 bp size marker.).
