Panel A : merged staining of anti-CD68 (magenta; Opal^™690), anti-PD-L1 (green; Opal^™520) and anti-PD1 (red; Opal^™570) on human tonsil.
Panel B : anti-PD-L1 stained on cells involved in T cell inhibition.
Panel C : anti-PD1 stained on antigen-stimulated T cells.
Panel D : anti-CD68 stained on macrophages.

The section was incubated in three rounds of staining : in the order of ab213363 and ab205921 for 30 mins, then ab237728 for 10 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.

The immunostaining was performed on a Leica Biosystems BOND^® RX instrument with an Opal^™ 4-color kit. Image acquisition was performed with Leica SP8 confocal microscope.

Multiplex immunohistochemistry - Anti-PD1 antibody [CAL20] - BSA and Azide free (AB251613)

Fluorescence multiplex immunohistochemical analysis of Human breast cancer tissue (formalin-fixed paraffin-embedded section).

Merged staining of Anti-PD-L1 (ab251611; cyan; Opal™ 520), Anti-Granzyme B (ab219803; yellow; Opal™ 540), Anti-PD1 (ab251613; magenta; Opal™ 570), Anti-pan Cytokeratin (ab264485; red; Opal™ 620), Anti-EpCAM (ab225894; red; Opal™ 620), Anti-CD8 alpha (ab251596; green; Opal™ 650) and Anti-FOXP3 (ab96048; orange; Opal™ 690). EpCAM and pan-cytokeratin share the same dye and color. Dyes are pseudo-colored for better contrast of the markers.

The immunostaining was performed on a Leica Biosystems BOND^® MAX instrument with an Opal™ 6-Plex Detection Kit (NEL821001KT, Akoya Biosciences^®).

The section was incubated in six rounds of staining; sequentially for ab251611 (1/750 dilution), ab219803 (1/250 dilution), ab251613 (1/750 dilution), ab264485 (0.5 μg/ml), ab225894 (1/1250 dilution), ab251596 (1/1500 dilution) and ab96048 (10 μg/ml); each using a separate fluorescent tyramide signal amplification system. EDTA based antigen retrieval (Leica Biosystems BOND^® Epitope Retrieval Solution 2, pH 9.0, 20 minutes) was used in between rounds of tyramide signal amplification to remove the antibody from the previous round, to avoid any cross-reactivity. DAPI (dark blue) was used as a nuclear counter stain.
Microscopy and pseudocoloring of individual Opal™ dyes was performed using a Vectra 3 Imaging System (Akoya Biosciences^®).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PD1 antibody [CAL20] - BSA and Azide free (AB251613)

This data was developed using ab237728, the same antibody clone in a different buffer formulation.

The BOND™ Polymer Refine Detection System on the BOND RX Automated Stainer (DS9800, Leica Biosystems, Wetzlar, Germany) was used for immunohistochemical labelling of formalin-fixed, paraffin-embedded (FFPE) tissues. The protocol includes a peroxide block, post-primary reagent, polymer detection, DAB chromogen, and haematoxylin counterstain, all automated to minimize variability. Antigen retrieval was performed by heat-induced epitope retrieval (HIER) for 20 minutes in Tris-EDTA buffer (BOND Epitope Retrieval Solution 2, AR9640, Leica Biosystems, Wetzlar, Germany). For mouse and rabbit antibodies, the sequence comprised peroxide block (10 min), primary antibody incubation (30 min), post-primary (10 min), polymer (10 min), DAB (10 min), and haematoxylin (8 min). For rat antibodies, an anti-rat step (1 : 300 dilution, Vector Laboratories, California, USA; 20 min) was included prior to polymer application (15 min).
