Figure 1: Immunohistochemical analysis of paraffin-embedded liver cancer tissues using NOS2 antibody with DAB staining.Pre-treat the sections with heat-mediated antigen retrieval using sodium citrate buffer (pH 6.0) (OM750020) for 2 minutes. Wash the sections with ddH₂O and PBS (OM750003). Block the tissue with 10% non-immune goat serum(OM760028) at room temperature for 30 minutes. Incubate the tissue with the primary antibody diluted at a ratio of 1:1500 at 4°C overnight. At room temperature, dilute the secondary antibody, Goat Anti-Rabbit IgG(H&L)-HRP (OM643487), at a ratio of 1:200 and incubate for one hour. Use DAB(OM760029)as the chromogenic agent. Counterstain the tissue with hematoxylin, and mount the tissue sections with neutral gum.

Figure 3: Immunofluorescence analysis of Panc-1 cells using NOS2 antibody (green). Blue: DAPI fluorescent DNA dye. Red: Actin filaments have been labeled with Omnimabs® 594-Phalloidin.Cells are fixed in 4% paraformaldehyde at room temperature for 20 minutes. Then, they are permeabilized with a PBS (OM750003) solution containing 0.1% Triton X-100(OM750021) at room temperature for 15 minutes. Subsequently, the cells are blocked with 10% non - immune goat serum(OM760028) at room temperature for 1 hour.The cells are incubated overnight at 4°C with the primary antibody diluted 1:100 in PBS. The secondary antibody, Omnimabs® 488 Goat Ant-Rabbit IgG(H&L) (Green,OM643486), is diluted at a ratio of 1:400 and incubated with the cells for 1 hour.Nuclear DNA is labeled with DAPI (Blue,OM643160). F-actin is stained with Omnimabs® 594-Phalloidin (Red,OM750007) diluted 1:100 for 30 minutes.
