Synthetic peptide conjugated to KLH derived from within residues 150 to the C-terminus of Human COX IV.
(Peptide available as ab16381.)
This antibody makes an effective loading control for mitochondria. COX IV is generally expressed at a consistent high level. However, be aware that many proteins run at the same 16kD size as COX IV - 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 Mouse monoclonal to COX IV antibody [20E8] (ab14744).
Our Abpromise guarantee covers the use of ab16056 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC||Use at an assay dependent concentration.|
|WB||Use a concentration of 0.5 µg/ml. Detects a band of approximately 15 kDa (predicted molecular weight: 17 kDa).Can be blocked with Human COX IV peptide (ab16381).|
|ICC/IF||Use a concentration of 1 µg/ml.|
|IHC-P||Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
ab16056 staining COX IV in Mouse heart tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and blocked with 5% serum for 1 hour at 21°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/600 ) for 12 hours at 4°C. A Cy5® donkey anti-rabbit secondary antibody was used as the secondary antibody.
ab16056 stained in Hela cells. Cells were fixed with 100% methanol (5min) at room temperature and incubated with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% triton for 1h at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab16056 at 1µg/ml and ab7291 (Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control) at 1/1000 dilution overnight at +4°C. The secondary antibodies were ab150120 (pseudo-colored red) and ab150081 (colored green) used at 1 ug/ml for 1hour at room temperature. DAPI was used to stain the cell nuclei (colored blue) at a concentration of 1.43µM for 1hour at room temperature
ab16056 staining COX IV in Mouse heart tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with acetone and blocked with 5% serum for 1 hour at 21°C. Samples were incubated with primary antibody (1/200) for 12 hours at 4°C. An Alexa Fluour® 594 donkey anti-rabbit secondary antibody was used as the secondary antibody.
ab16056 staining COX IV in breast tumour tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with 10% buffered formalin and blocked with 5% serum for 60 minutes at 21°C; antigen retrieval was by heat mediation in a 10mM sodium citrate buffer pH6. Samples were incubated with primary antibody (1/300 in blocking buffer) for 12 hours at 4°C. An Alexa Fluor® 647-conjugated donkey anti-rabbit IgG polyclonal (1/200) was used as the secondary antibody.
