CAL-62 cells were transduced with lentivirus co-expressing the Rluc (Renilla luciferase), mcherry, and puromycin genes under the control of the CMV promoter (Genecopoeia, Rockville, MD, USA). Stable clones were selected with puromycin (Sigma-Aldrich, St. Louis, MO, USA). CAL-62 and NK-92MI cells were retrovirally transduced to express both the effluc (enhanced firefly luciferase) and Thy1.1 genes. Thy1.1-positive cells were sorted by CD90.1 microbeads (Miltenyi Biotec, Bergisch Gladbach, Germany). The established stable cell lines expressing the Rluc and effluc genes were referred to as the CAL-62/R, CAL-62/F, and NK/F cells.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
