Figure 6 Immunohistochemistry Validation of PD-1 in Human Tonsil Tissue
Immunohistochemical analysis of paraffin-embedded human tonsil tissue using anti-PD-1 antibody (4065) at 5 μg/ml. Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4℃. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.

Figure 8 Immunohistochemistry Validation of PD-1 in Human Brain Tissue
Immunohistochemical analysis of paraffin-embedded human brain tissue using anti-PD-1 antibody (4065) at 2.5 μg/ml. Tissue was fixed with formaldehyde and blocked with 10% serum for 1 h at RT; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody overnight at 4℃. A goat anti-rabbit IgG H&L (HRP) at 1/250 was used as secondary. Counter stained with Hematoxylin.
