HEK293 Cell Line as a Platform to Produce Recombinant
HEK293 Cells for Transfection:
A Platform for Recombinant Proteins and Viral Vectors
HEK293 cells are widely used in biotechnology because they support efficient transfection, strong recombinant protein expression, and viral vector production in a human cellular background.
What Are HEK293 Cells?
HEK293 cells, also written as HEK 293, are a human-derived cell line commonly used in molecular biology, protein expression, and gene delivery research. Their ease of culture and high DNA uptake make them a preferred model for transfection workflows.
Why Are HEK293 Cells Used for Transfection?
High Transfection Efficiency
HEK293 cells readily take up plasmid DNA, supporting transient and stable expression studies.
Human Cell Background
They support mammalian protein folding and post-translational processing.
Easy Cell Culture
HEK293 cells are robust, scalable, and suitable for routine laboratory workflows.
HEK293 for Recombinant Protein Production
The HEK293 cell line is commonly used to produce recombinant proteins, including enzymes, cytokines, antibodies, receptors, and membrane proteins. Compared with bacterial expression systems, HEK293 provides a mammalian environment that can improve expression of complex human proteins.
HEK293 and Viral Vector Production
HEK293 and HEK293T cells are frequently used for viral vector workflows, including adenoviral, lentiviral, and AAV-related production systems. Their strong transfection performance makes them suitable for packaging plasmid-based systems.
