ICC/IF image of ab97993 stained MCF-7 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 ab97993 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) 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 formaldehyde fixed (4%, 10min) HeLa, Hek293,and HepG2 cells at 5ug/ml.
Western blot - Anti-Pumilio 1 antibody (ab97993)
Anti-Pumilio 1 antibody (ab97993) at 1 µg/ml + Mouse lung normal tissue lysate - total protein (ab29297) at 10 µg
The predicted molecular weight of Pumilio 1 is 127 kDa (SwissProt), however we expect to observe a banding pattern around 150 kDa. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
