LPS transfection:

LPS transfections were performed as previously described (Hagar 2011), with modifications. Briefly, 100 ng of rickettsial LPS or Salmonella LPS (List Biologicals) was added to Opti-Mem (Gibco), and 50 ng of Lipofectamine 2000 (Invitrogen) or DOTAP (Thermo-Scientific) was added to Opti-Mem and allowed to equilibrate for 5 min at room temperature. The LPS and Lipofectamine/DOTAP mixtures were combined and allowed to form complexes at room temperature for 30 min. Cell culture medium of BMM were replaced with Opti-Mem, and the LPS-transfection reagent complexes were added. Cells were centrifuged at 300 x g for 5 min, and then incubated at 4 hours at 37C. Cell medium was replaced with DMEM/F12 and 10% v/v fetal bovine serum for 20 hours. Cell lysates and medium were collected after a total of 24 hours post-transfection.
