293T-Dual™ Null Cells (ISG-SEAP/KI-[IFN-β]Lucia)

293T-Dual™ Null (ISG/KI-IFNb) cells are the parental cell line for the 293T-Dual™ STING (ISG/KI-IFNb) cells. They were generated by stable transfection with two different reporter genes (SEAP and Lucia luciferase).

These cells were generated from 293T which are known to have a non-functional STING pathway [2,3].

293T-Dual™ Null (ISG/KI-IFNb) cells are resistant to hygromycin and Zeocin™ .

Specifications

Antibiotic resistance: hygromycin, Zeocin™

Growth medium: DMEM, 4.5 g/l glucose, 2 mM L-glutamine, 10% (v/v) fetal bovine serum (FBS), 100 U/ml penicillin, 100 μg/ml streptomycin, 100 μg/ml Normocin™

Quality Control:

  • Reporter activity has been validated by stimulating the cells with human interferon-β (hIFN-β) and IRF3 activators, such as c-di-AMP and cGAMP.
  • The biallelic replacement of the hIFN-β coding sequence with the Lucia luciferase open reading frame (ORF) has been verified by PCR and sequencing. Furthermore, the inability to produce IFN-β has been confirmed by ELISA.
  • The cell line stability for 20 passages following thawing has been verified.

Guaranteed mycoplasma-free
