HEK293T Cells
HEK293T Cells for Transfection, Recombinant Protein Expression, and Viral Vector Production
HEK293T cells are among the most widely used mammalian cell lines in biotechnology and molecular biology. Their high transfection efficiency, rapid growth, and strong recombinant expression capabilities make them ideal for viral vector production, gene delivery, and protein expression workflows.
What Are HEK293T Cells ?
HEK293T cells are a modified derivative of the HEK293 human embryonic kidney cell line engineered to express the SV40 large T antigen. This feature enhances plasmid replication and significantly improves recombinant gene expression after transfection.
High Transfection Efficiency
HEK293T cells efficiently uptake plasmid DNA, supporting strong transient and stable expression workflows.
Enhanced Expression
SV40 large T antigen expression boosts episomal plasmid replication and recombinant protein production.
Easy Cell Culture
HEK293T cells are robust, fast-growing, and easy to maintain in routine mammalian cell culture systems.
Why Are HEK293T Cells Used for Transfection?
Researchers widely use HEK293T cells because they combine excellent DNA uptake, strong recombinant expression, and reliable growth characteristics. Their compatibility with plasmid-based systems makes them one of the most efficient mammalian transfection platforms available today.
