293T-Dual™ hSTING-R232 CellsNEW

293T-Dual™ hSTING-R232 Cells (ISG-SEAP/KI-[IFN-b]Lucia)

293T-Dual™ hSTING-R232 (ISG/KI-IFNb) cells were generated from 293T-Dual™ Null (ISG/KI-IFNb) cells by stable transfection of the R232 isoform of human STING (hSTING). Genomic studies indicate that this isoform, which contains an arginine at position 232 (R232), is the most prevalent with an isoform occurence of ~60% in the human population [1, 2]. This isoform is preferentially activated by 2’5’linkage-containing cGAMP isomers [3].

293T-DualhSTING-R232 (ISG/KI-IFNb) cells are resistant to blasticidinhygromycin and Zeocin™ .

Figures for this product

IRF induction (SEAP reporter)IFN-β induction (Lucia luciferase reporter)


Antibiotic resistance: blasticidinhygromycin and 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.
