Human TLR2 (NF-κB-SEAP / KI-[IL-8]Lucia) dual-reporter HEK293 cells
HEK-Dual™ hTLR2 (NF/IL8) cells were generated from HEK-Dual™ Null cells by stable transfection of the human TLR2 (hTLR2) and CD14 genes. Due to the knockout of TLR3 and TLR5, these cells enable the study of hTLR2 signaling without interference from other TLRs. They respond to very low concentrations of TLR2 agonists such as the synthetic lipopeptide Pam3CSK4. They do not respond to other TLR agonists or to the cytokine TNF-α (see validation sheet).
HEK-Dual™ hTLR2 (NF/IL8) cells are resistant to hygromycin B, Zeocin® and blasticidin. They should be maintained in growth medium supplemented with hygromycin B and Zeocin®.
