ICC/IF image of ab109865 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 (ab109865, 10µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse 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.

Complex II immunoprecipitation using antibody ab109865  crosslinked to protein G-agarose beads.  Complex II was immunoprecipitated from a lauryl maltoside detergent extract of 1000 ug bovine heart mitochondria in lane 1 and 500 ug human heart mitochondria in lane 2.  The gel was stained with coomassie brilliant blue.
