UltraFectin 293 Liposomal Transfection Reagent is widely used in molecular biology for efficient delivery of nucleic acids into mammalian cells, particularly HEK293 cells. It is highly effective for transient gene expression studies, enabling researchers to produce recombinant proteins, study gene function, and analyze regulatory elements. Its liposomal formulation ensures high transfection efficiency with minimal cytotoxicity, making it ideal for sensitive applications. Additionally, it is suitable for co-transfection experiments, allowing simultaneous delivery of multiple plasmids. Its versatility and reliability make it a preferred choice for optimizing protein production in biopharmaceutical research and gene therapy development.
