Hek293t biosafety

What are the advantages of HEK293T cells?
HEK293 cells are used in cancer research, vaccine development, protein production, signal transduction and protein interaction studies, drug testing, and receptor de-orphanization, just to list a few.
What biosafety level is HEK293T?
Biosafety Level 2 (BSL-2) protections apply to work with pathogens or infectious organisms associated with human diseases.
These organisms pose a moderate health hazard.
Centers for Disease Control and Prevention (CDC) guidelines (pdf) require BSL-2 containment for work with HEK 293 cell lines..
What do HEK293T cells do?
It is used in the production of adenoviral and adeno-associated viral vectors due to presence of the adenoviral E1A/B genes which provide helper functions during viral vector production.
In retroviral vector production, HEK293T is used due to the expression of the SV40 large T-antigen in the cell line..
What is HEK293T used for?
Besides for use in recombinant protein production, HEK-293 cells are used for propagation of adenoviral vectors, and HEK293T is an important line for propagating retroviral vectors.
In fact, several retroviral packaging cell lines are based on HEK-293T cells..
What is the difference between HEK293 and HEK293T?
The main difference is that HEK 293T cells express the SV40 large T antigen, while HEK 293 cells do not naturally express it.
This modification in HEK 293T cells enhances their transfection efficiency and viral packaging capabilities._{Jul 11, 2023}.
Where do HEK 293T cells come from?
Where do HEK293T cells come from? HEK293T cells are derived from HEK293 cells, which are derived from human embryonic kidney cells.
HEK293T cells have been genetically modified to express the SV40 large T antigen, enhancing their transfection efficiency and viral packaging capabilities._{Jul 11, 2023}.
HEK 293 Cells Limitations
Prone to bacterial contamination.Susceptible to viral contamination.Extended periods of culturing will result in the degradation of the cell's health.
Besides for use in recombinant protein production, HEK-293 cells are used for propagation of adenoviral vectors, and HEK293T is an important line for propagating retroviral vectors.
In fact, several retroviral packaging cell lines are based on HEK-293T cells.
HEK293T cells are derived from HEK293 cells expressing the simian virus 40 (SV40) large T antigen, which allows for the replication of plasmids containing the SV40 origin of replication, leading to high expression of protein.
Moreover, the 5th Edition of the CDC publication, Biosafety in Microbiological and Biomedical Laboratories (BMBL),recommends that human and other primate cells should be handled using Biosafety Level 2 (BSL-2) practices and containment.

According to the CDC, the HEK293 cell line is Biosafety level 2. BPS recommends checking with your local federal, state, and institutional regulations. If in doubt, we recommend using the highest appropriate biosafety level requirements.

According to the CDC, the HEK293 cell line is Biosafety level 2.

Biosafety level 2 practices and containment facilities for all activities involving HEK-293 cell lines (9). Procedures that may generate droplets (aerosols, splashes, sprays) with HEK-293 cell lines and their derivative should be handled in a Class II BSC with BSL-2 PPE (lab coat and gloves) (9).

The cell line was initiated by the transformation and culturing of normal HEK cells with sheared adenovirus 5 DNA. A portion of human adenovirus 5, nucleotides

These organisms pose a moderate health hazard. Centers for Disease Control and Prevention (CDC) guidelines (pdf) require BSL-2 containment for work with HEK 293
