About This Simulation

In the Cell Culture basics – Transfection simulation you will transfect a melanoma cell line using a lipid-based reagent in order to overexpress a gene that is involved in skin cancer. You will prepare the cells and the reagents and you will use a DNA plasmid carrying the green fluorescent protein as reporter. Will you be able to get fluorescent cells?
