Flow Cytometry - Anti-CD276 antibody [MM0104-20J12] (AB89133)

Overlay histogram showing THP1 cells stained with ab89133 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab89133, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2μg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed.

Flow Cytometry - Anti-CD276 antibody [MM0104-20J12] (AB89133)

Flow cytometry overlay histogram showing wild-type HEK293 (green line) and CD276 knockout HEK293 (ab266658) cells stained with ab89133 (red line). The cells were incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab89133) (1x10⁶ in 100μl at 0.2 μg/ml) for 30 min at 4^oC.

The secondary antibody Goat anti-mouse IgG H&L (Alexa Fluor^® 488, pre-adsorbed) (ab150117) was used at 1/2000 for 30 min at 4°C.) cells stained with ab89133 (red line). The cells were incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab89133) (1x10⁶ in 100μl at 0.2 μg/ml) for 30 min at 4°C.

Isotype control antibody was mouse IgG1κ (ab170190) used at the same concentration and conditions as the primary antibody (wild-type HEK293 - black line CD276 HEK293 knockout - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity).

Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD276 antibody [MM0104-20J12] (AB89133)

IHC image of ab89133 staining in Human placenta formalin fixed paraffin embedded tissue section, performed on a Leica Bond^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab89133, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
