Panel A : merged staining of anti-CD8 alpha (magenta; Opal™690), anti-CD4 (green; Opal™520) and anti-CD19 (red; Opal™570) on human spleen.
Panel B : anti-CD8 alpha stained on cytotoxic T cells.
Panel C : anti-CD4 stained on T helper cells.
Panel D : anti-CD19 stained on B cells.

Sections were treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins before antibody incubation. The section was incubated in three rounds of staining : in the order of ab245118 for 30 mins, then ab238798 and ab237772 for 10 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system.

DAPI was used as a nuclear counterstain.

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.

Flow cytometric analysis of human peripheral blood mononuclear cells (PBMC) labeling CD8 alpha with ab245118 at 1/400 (right panel) compared with a Rabbit monoclonal IgG (ab172730) (left panel). Goat anti rabbit IgG (Dylight^® 488, ab98462) at 1/2000 dilution was used as the secondary antibody.

Cells were stained with rabbit IgG (Left) or anti-CD8 alpha RabMab (Right). Then stained with Alexa Fluor^® 647-conjugated anti-CD4. The expressions of CD4 and CD8 alpha are mutually exclusive.

Gated on viable lymphocytes.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab245118).
