General notes
This antibody clone is manufactured by Abcam.
This antibody makes an effective loading control for mitochondria. COXIV is generally expressed at a consistent high level. However, be aware that many proteins run at the same 16kD size as COXIV - our VDAC1 / Porin antibody makes a good alternative mitochondrial loading control for proteins of this size. Some caution is required when using this antibody as a loading control as COXIV expression can vary under some manipulations. An alternative mitochondrial loading control is Rabbit polyclonal to COX IV antibody (ab16056).
If you require this antibody in a particular buffer formulation or a particular conjugate for your experiments, please contact orders@abcam.com or you can find further information here.

The cells were methanol/acetone fixed at -20C for 5 minutes, blocked with BSA and then incubated with the antibody for 16 hours. The positive tissue was colocalised with a mitotracker (mitotrackers are a series of patented mt-selective stains that are concentrated by active mt and well retained during cell fixation). An Alexa-Fluor ® 488 conjugated goat anti-mouse antibody was used as the secondary. The image shows COXIV staining in green and DAPI staining in blue.

The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab14744, 0.5µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1](ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. -
