  • This image shows human colon carcinoma tissue stained with ab64885 at 1/50-1/100 dilution; with (+) and without (-) the immunising peptide.
  • All lanes : Anti-COX IV antibody (ab64885) at 1/500 dilution

    Lane 1 : extracts from A549 cells (5-30µg total protein)
    Lane 2 : extracts from A549 cells (5-30µg total protein) and 5-10µg of the immunising peptide.

    Observed band size : 20 kDa
  • ICC/IF image of ab64885 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 (ab64885, 1µg/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.
