This video describes the RNA extraction protocol from miRNA transfected lung cancer cells. This approach can be used to identify a combinatorial miRNA treatment activity in halting the cell cycle and angiogenesis.
1. miR-143 and miR-506 transfection
CAUTION: Use latex gloves, protective eyeglasses, and a laboratory coat while performing the described experiments. When required, use the biosafety cabinet with the cabinet fan on, without blocking the airways or disturbing the laminar airflow. Always set the protecting glass window to the appropriate height, as described by the manufacturer.
2. RNA extraction
