Functional: Human TLR3 Stable Cell Line [NBP2-26267] - Functional analysis of the TLR3 stable cell line. The assay was performed using the NF-kB SEAPorter? Assay Kit. The Vector control stable cell line and TLR3 stable cell line were transfected with NF-kB/SEAP reporter plasmid for 16 h. Cells were stimulated with Polyinosinic-polycytidylic acid (Poly(I:C)) for 24 h followed by SEAP assay.
