Transformed from MDA-MB-231 cells by lentivirus, expressing the firefly luciferase gene III and enhanced GFP fluorescent marker. The Luciferase and GFP was co-expressed under the same suCMV promoter as separated two proteins(not as fusion). The Puromycin marker was expressed under Rsv promoter.Each cell demonstrated strong GFP Fluorescent signal and high level of luminescence signal via luciferase assay. Note: this is pooled stable ell population, not originated from a single cell colony. Thus you will observe the uneven GFP signal intensity amount cells.
