B16-Blue™ ISG-KO-STING cells can be used for the study of the STING signaling pathway and for the detection of bioactive murine types I and II IFNs by monitoring the activation of the JAK/STAT pathway.
B16-Blue™ ISG-KO-STING cells were generated from the B16-Blue™ ISG cell line, a murine B16- F1 melanoma-derived cell line, through stable knockout of the STING gene. They express the secreted embryonic alkaline phosphatase (SEAP) reporter gene under the control of the I-ISG54 promoter which is comprised of the IFN-inducible ISG54 promoter enhanced by a multimeric ISRE.
B16-Blue™ ISG-KO-STING cells do not respond to cytosolic DNA, DMXAA, canonical and non-canonical CDNs while retaining the ability to respond to type I and type II IFNs.
Stimulation of these cells with IFN triggers the activation of the I-ISG54 promoter and the production of SEAP. Levels of SEAP in the supernatant can be easily determined using QUANTI- Blue™, a reagent that turns purple/blue in the presence of SEAP, by reading the OD at 620-655 nm.
