  • 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.

    ab14744 at 1/100 staining MCF-10A cells (human mammary epithelial cell line) by ICC/IF. 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.

    Overlay histogram showing HeLa cells stained with ab14744 (red line). 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.

Kundin hat diese AKs am 10.1.2011 bestellt, kamen als Lyophilisat und wurden eingefroren bei -20C
Ist das okay?
Sind die Klone dieselben?

Vielen Dank für Ihren Anruf.
