ATCC credible cells lead to incredible research results ATCC has the world’s largest and most extensive product catalog of human and animal cell lines for research purposes. The cell biology collection includes more than 4,000 continuous cell lines available by species, tissue/disease types, and signaling pathways.
What is the difference between 293 and 293T cells?
The key difference between HEK293 and HEK293t is that HEK293 is an immortalized cell line derived from the embryonic human kidney that is transfected with sheared human adenovirus type 5DNA while HEK293t is a daughter cell line derived from HEK293 original cell line that is transfected with a plasmid vector carrying …
How do you transfect HEK293T cells?
Transfecting HEK 293 cells Plate 0.5 -1.25×105 cells per well in 0.5 mL of complete growth medium. Cell density should be 50–80% confluent on the day of transfection. (Optional) The day of transfection, remove growth medium from cells and replace with 0.5 mL of complete growth medium.
Where do HEK293T cells come from?
Origins of the HEK293 Cell Line HEK293 is a cell line derived from human embryonic kidney cells grown in tissue culture. They are also known, more informally, as HEK cells. This particular line was initiated by the transformation and culturing of normal HEK cells with sheared adenovirus 5 DNA.
What are calu 3 cells?
Calu-3 is a non-small-cell lung cancer cell line that grows in adherent culture and displays epithelial morphology. These cells have constitutively active ErbB2/Her2 due to amplification of the ERBB2 gene.
Where did 293t cells come from?
History. HEK 293 cells were generated in 1973 by transfection of cultures of normal human embryonic kidney cells with sheared adenovirus 5 DNA in Alex van der Eb’s laboratory in Leiden, the Netherlands. The cells were obtained from a single, aborted or miscarried fetus, the precise origin of which is unclear.
Why do viruses have 293t cells?
The reason for the preference of HEK293T cells is that the presence of the SV40 T-antigen in the producer cells renders them more efficient for vector production. In addition, HEK293T cells show increased cell growth and transfection efficiency in comparison to HEK293 cells.
What is 293ft cell line?
Description The 293FT Cell line is ideal for generating high-titer lentivirus using the ViraPower™ Lentiviral Expression System. The 293FT Cell Line is a fast-growing, highly transfectable clonal isolate derived from human embryonal kidney cells transformed with the SV40 large T antigen.
Is the 293ft cell line suitable for lentiviral production?
The 293FT Cell Line is a very suitable host for lentiviral production. The 293FT Cell Line is derived from the 293F Cell Line (see below) and stably expresses the SV40 large T antigen from the pCMVSPORT6TAg.neo plasmid.
Which plasmid is used in the 293ft cell line?
The 293FT Cell Line is derived from the 293F Cell Line (see below) and stably expresses the SV40 large T antigen from the pCMVSPORT6TAg.neo plasmid. Expression of the SV40 large T antigen is controlled by the human cytomegalovirus (CMV) promoter and is high-level and constitutive.
Can I use an alternative product for my 293T cell line?
If you use alternative products, the quality and effectiveness of the item may be affected. The 293T cell line, originally referred as 293tsA1609neo, is a highly transfectable derivative of human embryonic kidney 293 cells, and contains the SV40 T-antigen. This cell line is competent to replicate vectors carrying the SV40 region of replication.
