Our Abpromise guarantee covers the use of ab25734 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
IHC-P: 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB: Use at a concentration of 1 - 5 µg/ml. Detects a band of approximately 65 kDa (predicted molecular weight: 65 kDa).
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionInteracts with centromeric heterochromatin in chromosomes and binds to a specific subset of alphoid satellite DNA, called the CENP-B box. May organize arrays of centromere satellite DNA into a higher order structure which then directs centromere formation and kinetochore assembly in mammalian chromosomes.
Sequence similaritiesContains 1 HTH CENPB-type DNA-binding domain.
Contains 1 HTH psq-type DNA-binding domain.
Cellular localizationNucleus. Chromosome > centromere.

Image courtesy of Human Protein Atlas. ab25734 staining CENPB in Human skin, showing nuclear staining in the epidermis and dermal layer. Paraffin embedded human skin tissue was incubated with ab25734(1/100 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.
ab25734 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues. Further results for this antibody can be found at www.proteinatlas.org
ab25734 (1/1000) staining CENPB in HeLa cells (green). Cells were fixed with methanol and counterstained with DAPI in order to highlight the nucleus (red). Please refer to abreview for further experimental details.
ICC/IF image of ab25734 stained human HeLa cells. The cells were 4% PFA fixed (10 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab25734, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. 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). DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in HEK 293 cells.
