Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: LC3B knockout HAP1 cell lysate (20 µg)
Lane 3: Human brain tissue lysate (20 µg)
Lane 4: U87MG cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab63817 observed at 16 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab63817 was shown to recognize LC3B in wild-type HAP1 cells along with additional cross reactive bands. No band was observed when LC3B knockout samples were examined. Wild-type and LC3B knockout samples were subjected to SDS-PAGE. ab63817 and ab8245 (loading control to GAPDH) were diluted 1 µg/mL and 1/10,000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.

ab63817 staining LC3B in HeLa cells +/- Chloroquine (50μM, 24 hours). The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab63817 at 1μg/ml and ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 594), at 1/250 dilution (shown in pseudocolor red) followed by a further incubation at room temperature for 1h with a goat secondary antibody to Rabbit IgG (Alexa Fluor® 488) (ab150081) at 2 μg/ml (shown in green). Nuclear DNA was labelled with DAPI (shown in blue).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

IHC image of LC3B staining in human hippocampus 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 ab63817, 1µg/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.
