    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 : 32 kDa
    Observed band size : 35 kDa (why is the actual band size different from the predicted?)

    Exposure time : 8 minutes
  • ICC/IF image of ab103998 stained HeLa cells. The cells were 4% formaldehyde 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 ab103998 at 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 Hek293, HepG2, and MCF-7 formaldehyde fixed cells at 5ug/ml and also in HeLa, Hek293, HepG2, and MCF-7 Methanol fixed cells at 5ug/ml.
