Live-cell imaging of NF-κB immune response in Drosophila S2* cells 405 minutes after stimulus, including nuclear NF-κB and transcription of Dpt gene.
Cells were adhered to glass-bottom wells coated with concanavalin A (a lectin protein), and stimulated with 100 µg/mL DAP-type peptidoglycan (PGN).
Microscopy Setup
Imaging was performed on a Nikon A1R point-scanning confocal microscope equipped with high-sensitivity GaAsP PMTs and a 60× oil immersion objective (NA = 1.4). Acquisition was controlled via Nikon Elements software.
