For immunofluorescence studies, we cultured cells extracted from full-thickness samples12 (link). The cells were grown on cover slips with Rat Tail Collagen I (Gibco, Invitrogen) coating, and fixed with methanol for 5 min at −20 °C56. The cover slip samples were incubated one hour at room temperature with the MTCO2 (Abcam, ab3298) and CARD6 antibodies. Alexa Fluor 555 and 488 conjugated IgGs (Invitrogen, Molecular Probes) were used as secondary antibodies and the nuclei stained with DAPI (Sigma-Aldrich). The pictures were taken with Zeiss LSM 5 Duo confocal microscope.
