All lanes : Anti-MRP4 antibody [M4I-10] (ab15602) at 20 µg/ml
Lane 1 : Wild-type HAP1 whole cell lysate
Lane 2 : ABCC4 (MRP4) knockout HAP1 whole cell lysate
Lysates/proteins at 20 µg per lane.
Predicted band size: 159 kDa
Lanes 1 - 2: Merged signal (red and green). Green - ab15602 observed at 200-250 kDa. Red - loading control, ab176560, observed at 50 kDa.
ab15602 was shown to specifically react with MRP4 in wild-type HAP1 cells as signal was lost in ABCC4 (MRP4) knockout cells. Wild-type and ABCC4 (MRP4) knockout samples were subjected to SDS-PAGE. Ab15602 and ab176560 (Rabbit anti-alpha Tubulin loading control) were incubated overnight at 4°C at 20 μg/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Rat IgG H&L (IRDye® 800CW) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
HC image of MRP4 staining in Human lung adenocarcinoma formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ system using the standard protocol B. 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 ab15602, 10µg/ml, for 15 mins at room temperature. A Goat anti-Rat biotinylated secondary antibody was used to detect the primary, and visualized using an HRP conjugated ABC 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.

Cells were fixed with paraformaldehyde and blocked with 3% BSA in PBS for 1 hour at room temperature; antigen retrieval was by 0.1% Triton X-100/PBS. Samples were incubated with primary antibody (1/100 in 0.5% BSA-PBS) for 2 hours at room temperature. An AlexaFluor®488-conjugated goat anti-rabbit IgG (1/1500) was used as the secondary antibody.
