Anti-HEC1 antibody [9G3] (ab3613)

Immunocytochemistry/ Immunofluorescence - HEC1 antibody [9G3] (ab3613)

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).

Western blot - HEC1 antibody [9G3] (ab3613)

ab3613 at a 1/1000 dilution staining ~ 80 kDa HEC 1 in Hela cell lysate (30µg per well) by Western blot.

Immunoprecipitation - Anti-HEC1 antibody [9G3] (ab3613)

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 70^oC; 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.

Immunofluorescence - HEC1 antibody [9G3] (ab3613)

HeLA cells were stained with anti-HEC1 (ab2613; in green) and DAPI (blue) in panel 1, and with anti-HEC1(green) and SH-CREST (red) to stain the centromeres in panel 2.

Fix the cells 30 minutes on ice in 4% formaldehyde in PEM. Quench autofluorescence 2 x 5 min. with 1 mg/ml Na borohydride or 100 mM ammonium chloride in PEM. Permeablize 30 min. with 0.5% TX-100 in PEM. Block 30 minutes in 5% milk in TBST. Primary antibody incubated at 1/1000 overnight at 4oC diluted in 5% milk in TBST. Secondary antibody 1 hour at RT diluted in 5% milk in TBST. Post-fix 20 min. on ice in 4% formaldehyde in PEM. Quench autofluorescence 2 x 5 min. 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.

Flow Cytometry - Anti-HEC1 antibody [9G3] (ab3613)

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.
