The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 15 kDa (predicted molecular weight: 15 kDa).
ICC/IF Use a concentration of 5 µg/ml.


  • FunctionProbably involved in formation of autophagosomal vacuoles (autophagosomes).
  • Tissue specificityMost abundant in heart, brain, skeletal muscle and testis. Little expression observed in liver.
  • Sequence similaritiesBelongs to the MAP1 LC3 family.
  • Post-translational
    The precursor molecule is cleaved by APG4B/ATG4B to form LC3-I. This is activated by APG7L/ATG7, transferred to ATG3 and conjugated to phospholipid to form LC3-II.
  • Cellular localizationCytoplasm > cytoskeleton. Endomembrane system. Cytoplasmic vesicle > autophagosome membrane. LC3-II binds to the autophagic membranes.

  • Predicted band size : 15 kDa

    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 when LC3B knockout samples were used, along with additional cross-reactive bands. 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 h at room temperature before imaging.

  • Immunocytochemical analysis of HeLa cells, labeling LC3B with ab63817 (1/200 with PBS for 16 hours at 22°C). Cells were methanol fixed, immunofluorescently labeled, adn counterstained with DAPI.

  • IHC image of LC3B staining in human hippocampus formalin fixed paraffin embedded tissue section, performed on a Leica BondTM 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.
  • ICC/IF image of ab63817 stained PC12 cells. The cells were 100% Methanol fixed (5 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab63817, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
