Murine Type I IFNs Sensor Cells
B16-Blue™ IFN-α/β cells allow the detection of bioactive murine type I IFNs by monitoring the activation of the JAK/STAT/ISGF3 pathway and/or IRF3 pathway.
They derive from the murine B16 melanoma cell line of C57BL/6 origin after stable transfection with a SEAP reporter gene under the control of the IFN-α/β-inducible ISG54 promoter enhanced by a multimeric ISRE.
B16-Blue™ IFN-α/β cells do not respond to IFN-γ, due to the inactivation of IFN-γ receptor. B16-Blue™ IFN-α/β cells respond specifically to mIFN-α/β and do not respond to human IFN-α/β.
Stimulation of B16-Blue™ IFN-α/β cells with murine IFN-α or IFN-β, or type I IFN inducers, such as poly(I:C), poly(dA:dT) or 5’ppp-dsRNA delivered intracelluarly, triggers the production of SEAP by the activation of the IRF-inducible promoter.
Levels of SEAP can be easily monitored using the detection medium QUANTI-Blue™.
RIG-I activation with 5’ppp-dsRNA can be easily monitored using B16 Blue™ ISG cells, an IFN regulatory factor (IRF)-inducible secreted embryonic alkaline phosphatase (SEAP) reporter cell line. B16-Blue™ ISG cells respond to stimulation with 5’ppp-dsRNA and Poly(I:C). The 5’ppp-dsRNA Control (non-phosphorylated) does not induce any response in B16-Blue™ ISG cells. Levels of SEAP is determined by colorimetric measurement using QUANTI-Blue™ and reading optical density (O.D.) at 630-655 nm.
Stimulation of B16-Blue™ IFN-α/β cells by recombinant human and murine IFN-α and IFN-β was assessed by measuring the levels of SEAP using QUANTI-Blue™.
