Flow Cytometry - Anti-CD68 antibody [SP251] - BSA and Azide free (AB271959)

Flow cytometric analysis of Raji (human Burkitt's lymphoma cell line) cells labeling CD68 with ab192847 at 1/100 dilution (green) compared with a negative control rabbit IgG (blue).

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab192847).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD68 antibody [SP251] - BSA and Azide free (AB271959)

Formalin-fixed, paraffin-embedded human tonsil tissue stained for CD68 using ab192847 at 1/100 dilution in immunohistochemical analysis.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD68 antibody [SP251] - BSA and Azide free (AB271959)

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human tonsil tissue sections labeling CD68 with ab192847 at 1/100 dilution (0.184 μg/ml) (incubated for 10 minutes at room temperature). Heat mediated antigen retrieval was performed with sodium citrate buffer (pH 6.0, epitope retrieval solution 1) for 20 minutes. Goat Anti-Rabbit & Mouse IgG (HRP) was used as the secondary antibody. Hematoxylin was used as a counterstain. Negative control : PBS instead of the primary antibody.

Positive staining on the macrophages in human tonsil, performed on a Leica Biosystems BOND^® RX instrument.

Multiplex immunohistochemistry - Anti-CD68 antibody [SP251] - BSA and Azide free (AB271959)

Fluorescence multiplex immunohistochemical analysis of normal human tonsil tissue (formalin-fixed paraffin-embedded section).

Merged staining of anti-PD1 (ab237728; orange; Opal™520) anti-PDL1 (ab237726; green; Opal™540) anti-CD68 (ab192847; yellow; Opal™570) anti-CD3 epsilon (ab16669; red; Opal™620) anti-Ki67 (ab16667; light blue; Opal™650) and anti-PanCK (ab7753; grey; Opal™690).

The immunostaining was performed on a Leica Biosystems BOND^® RX instrument with an Opal™ 7-color automation IHC kit (NEL821001KT Akoya Biosciences^®).

The section was incubated in six rounds of staining; in the order of ab237728 (1/500 dilution), ab237726 (1/500 dilution), ab192847 (1/300 dilution), ab16669 (1/300 dilution), ab16667 (1/200 dilution) and ab7753 (1/200 dilution); each using a separate fluorescent tyramide signal amplification system.

Sodium citrate antigen retrieval (Leica ER1 pH6.0 30 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 Polaris.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab192847).
