LP433078 is a cell line derived from the human embryonic kidney 293 (HEK 293) cell line. It is a frequent host for transfection experiments and its cell type is the most widely employed for ectopic expression studies. It is a commonly used cell line for studies in molecular biology, cell biology, biochemistry and cloning. It is frequently used for stable cell line production, as well as for clonal growth assay and recombinant protein expression. It can be used in many viral packaging experiments, or for generating recombinant viral vectors. It is used as a model cell line for studying gene regulation, as well as for generating transgenic cell lines.
