    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 53 kDa
    Observed band size : 55 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 125 kDa,140 kDa,30 kDa,44 kDa,48 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 4 minutesThe PNPLA3 sequence contains two glycosylation sites (Swissprot data). The additional band close to the band of interest might be a glycosylated form of PNPLA3. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
  • ICC/IF image of ab81874 stained MCF7 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 (ab81874, 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. This antibody also gave a positive result in 4% PFA fixed (10 min) HeLa and HepG2 cells at 5µg/ml.
