Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: CPT1A knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: MCF-7 cell lysate (20 µg)

Lanes 1 - 4: Merged signal (red and green). Green - ab128568 observed at 88 kDa. Red - loading control, ab181602, observed at 37 kDa.

ab128568 specifically detected the expected band for CPT1A in wild-type HAP1 cells. No band was observed in CPT1A knockout cells. Wild-type and CPT1A knockout samples were subjected to SDS-PAGE. ab128568 and ab181602 (loading control to GAPDH) were diluted at 1 μg/mL and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Mouse IgG H&L (IRDye^® 800CW) preadsorbed (ab216772) and Goat Anti-Rabbit IgG H&L (IRDye^® 680RD) preadsorbed (ab216777) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

IHC image of CPT1A staining in human normal kidney 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 ab128568, 0.5µg/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.

Overlay histogram showing HeLa cells stained with ab128568 (red line) or no primary antibody (black line). The cells were fixed with 4% paraformaldehyde (15 min) and then permeabilized with 0.1% Triton X-100 in PBS, 3% BSA for 10 min. The cells were then incubated in 3% BSA in PBS for 10 minutes to block non-specific protein-protein interactions followed by the antibody (ab128568, 1µg/mL) for 60 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96871) at 1/1000 dilution for 30 min.
