Immunofluorescence (IF) staining was constructed by the method described in many studies. The tissue was embedded in paraffin and cut into 5-
µm sections beforehand. All slides were deparaffinized, rehydrated in xylene, 100%, 95%, 85%, 75% ethanol, and PBS, and constantly stained with 10% antigen retrieval solution for 10 min.
BSA (1%, Sangon) as the blocking buffer was incubated at room temperature for 15 min. The primary antibody was added and incubated at 4°C overnight. Then, the secondary antibody, and 4′,6-diamidino-2-phenylindole (DAPI) (Aladdin) were added to this procedure. The antibodies used in this section involved as follows:
NF-κB p-p65 antibody (1:200, Affinity, Jiangsu, China), CD68 (1:50, Santa Cruz, Santa Cruz, CA, USA), iNOS (1:100, ABclonal),
Cy3 labeled goat anti-mouse IgG (1:200, Invitrogen, Carlsbad, CA, USA),
Cy3 labeled goat anti-rabbit IgG (1:200, Invitrogen),
FITC labeled goat anti-mouse IgG (1:200, Abcam, Cambridge, UK). The immunofluorescence images were taken and preserved using an
OLYMPUS-BX53 microscope (OLYMPUS, Tokyo, Japan).
