  • All lanes : Anti-ACSS2 antibody (ab66038) at 1 µg/ml

    Lane 1 : Wild-type HAP1 whole cell lysate
    Lane 2 : ACSS2 knockout HAP1 whole cell lysate
    Lane 3 : HepG2 whole cell lysate
    Lane 4 : U-87 MG whole cell lysate

    Lysates/proteins at 20 µg per lane.

    Predicted band size: 79 kDa
    Observed band size: 80 kDa
    why is the actual band size different from the predicted?

    Lanes 1 - 4: Merged signal (red and green). Green - ab66038 observed at 80 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab66038 was shown to recognize ACSS2 in wild-type HAP1 cells as signal was lost at the expected MW in ACSS2 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and ACSS2 knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. Ab66038 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1 ug/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

    Performed under reducing conditions.

    Predicted band size: 79 kDa
    Observed band size: 79 kDa
    Additional bands at: 100 kDa, 38 kDa, 45 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 30 seconds
  • ACSS2 was immunoprecipitated using 0.5mg HepG2 whole cell extract, 5µg of Rabbit polyclonal to ACSS2 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, HepG2 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab66038.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 79kDa: ACSS2.

  • IHC image of ACSS2 staining in human liver carcinoma 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 ab66038, 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.

  • ICC/IF image of ab66038 stained HeLa cells. The cells were 4% PFA fixed (10 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 (ab66038, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 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. This antibody also gave a positive result in 100% methanol fixed (5 min) HeLa cells at 1µg/ml.
