Updated project metadata. BMDCs from WT, Fcgr2b-/- and Stinggt/gt were cultured, then stimulated with DMXAA for 3 and 6 hr. Cells were collected and lysed with 1 % IGEPAL CA-630, 0.5% TritonX-100, 150 mM NaCl, 50 mM Tris pH 7.4, 5% glycerol, 100 mM beta-Glycerophosphate, 2 mM Na3VO4 and 1X proteases inhibitor cocktail (Roche). First, antibody were mixed with the magnetic beads by adding 10 µg of STING antibody with 400 ug of SureBeads™ Protein A magnetic beads (Biorad, California, USA) and incubated for 1 hour at room temperature. Then, Protein lysates were added and incubated with antibody-conjugated beads for overnight at 4oC. After incubation, the beads were washed 3 times with wash buffer (150 mM NaCl and 50 mM Tris-HCL pH 7.4). Samples were eluted by adding 5X laemmli buffer and, boiled 950C for 10 minutes. The eluted protein samples were separated by 10 % SDS-PAGE gel. The STING interacting proteins from co-IP were analyzed by in-gel digestion followed by LC-MS/MS analysis.
