ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
Use at an assay dependent concentration.
1/1000. Detects a band of approximately 80 kDa (predicted molecular weight: 74 kDa).
Use at an assay dependent concentration.
Acts as a component of the essential kinetochore-associated NDC80 complex, which is required for chromosome segregation and spindle checkpoint activity. Required for kinetochore integrity and the organization of stable microtubule binding sites in the outer plate of the kinetochore.
Belongs to the NDC80/HEC1 family.
Expression peaks in mitosis.
Phosphorylation begins in S phase of the cell cycle and peaks in mitosis. Phosphorylated by NEK2. May also be phosphorylated by AURKA and AURKB.
Nucleus. Chromosome > centromere > kinetochore. Localizes to kinetochores from late prophase to anaphase. Localizes specifically to the outer plate of the kinetochore.

ab3613 at 1/1000 dilution staining HeLa cells by ICC/IF. The cells were formaldehyde fixed and blocked with 5% BSA prior to incubation with the antibody for 2 hours. An Alexa-Fluor ® 488 conjugated goat anti-mouse antibody was used as the secondary.
ab3613 at a 1/1000 dilution staining ~ 80 kDa HEC 1 in Hela cell lysate (30µg per well) by Western blot. ab3613 at a 1/1000 dilution staining ~ 80 kDa HEC 1 in Hela cell lysate (30µg per well) by Western blot.
HEC1 was immunoprecipitated using 0.5mg Hela whole cell extract, 10µg of Mouse monoclonal to HEC1 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-). The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation. Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab3613. Secondary: Goat polyclonal to mouse IgG light chain specific (HRP) at 1/5000 dilution. Band: Band: 76kDa: HEC1.
Anti-Hec1 antibody (ab3613) labels the kinetochores of mitotic cells in LLCPK1 (Sus scrofa kidney epithelial cell line) cell lines. Merge shows an overlay of DNA (stained with DAPI, red) and Hec1 (green). This image was kindly supplied as part of the review submitted by Marko Kallio.
Overlay histogram showing HeLa cells stained with ab3613 (red line). The cells were fixed with 4% paraformaldehyde (10 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 (ab3613, 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 IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HeLa cells fixed with 80% methanol (5 min) /permeabilized in 0.1% PBS-Tween used under the same conditions.
