RelevanceCENPE is a 250-300 kDa human centromere-associated kinesin-like motor protein that accumulates in G2 phase. In contrast to other centromere proteins, CENPE is not detected at centromeres during interphase, and first appears at the centromere region of chromosomes during prometaphase. CENPE function is required for the transition from metaphase to anaphase. CENPE is probably one of the motors responsible for mammalian chromosome movement and/or spindle elongation.
Cellular localizationAssociates with kinetochores during congression, relocates to the spindle midzone at anaphase, and is quantitatively discarded at the end of the cell division.

ab5093 at 1/500 staining human fibrosarcoma (HT1080) cells by ICC/IF. The cells were treated with 0.1-0.2ug/mL colcemid for 45-60 minutes, then swollen in hypotonic buffer for 8 minutes and centrifuged onto glass slides. Cells were blocked in 1X PBS + 1% BSA + 0.5% Triton X-100 (blocking buffer) for 30 minutes at room temperature. The antibodies were diluted 1/300-1/500 in blocking buffer and incubated overnight at 4 degrees C. ab5093 was detected with Alexa Fluor 488-donkey anti-mouse for 1-2 hours at room temperature.
HeLa cells were stained with ab5093, anti-CENPE (in green) in panel one, and with ab5093 and SH-CREST (red), which stains the centromeres, in panel 2. Fix cells for 30 minutes on ice in 4% formaldehyde in PEM. Quench autofluorescence 2 x 5 minutes with 1 mg/ml Na borohydride or 100 mM ammonium chloride in PEM. Permeablize 30 minutes with 0.5% TX-100 in PEM. Block 30 minutes in 5% milk in TBST. Primary antibody overnight at 4oC diluted 1/250 in 5% milk in TBST. Secondary antibody was incubated for 1 hour at RT diluted in 5% milk in TBST. Post-fix 20 minutes on ice in 4% formaldehyde in PEM. Quench autofluorescence 2 x 5 minutes with ammonium chloride in PEM. Counterstain with DAPI in TBST. Mount with ProLong Gold antifade reagent from Invitrogen. Notes: Ample washing between each step. TBST = Tris buffered saline + 0.1% Tween. PEM = 80 mM K-PIPES, pH 6.8, 5 mM EGTA, 2 mM MgCl2.

Overlay histogram showing HeLA cells stained with ab5093 (red line). The cells were fixed with 100% 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 (ab5093, 1µg/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.
