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

Immunocytochemistry/ Immunofluorescence analysis of HeLa cells labeling HEC1/HEC at the kinetochore with ab3613 at 1/500 (green). Cells were fixed in 4% paraformaldehyde at room temperature for 15 minutes. The cells were permeabilized with 0.1% Triton X-100 in PBS at room temperature for 4 minutes. The cells were blocked in 2.5% BSA/PBS at room temperature for 30 minutes. ab3613 was incubated at 4°C overnight. The secondary antibody was a Rabbit IgG antibody (Alexa Fluor 488), 1/2000 (keep from light), room temperature for 1hour. Washing with PBS 3 x 3 minutes. Red: alpha Tubulin 4a, a cytoskeleton marker, stained by an alpha Tubulin 4a antibody.
Blue: Hoechst 33342 staining. 

Synchronized condition: Suggest to treat cells with Nocodazole (10ng/ml, 24hr).

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

HEC1/HEC was immunoprecipitated using 0.5mg Hela whole cell extract, 10µg of Mouse monoclonal to HEC1/HEC 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/HEC.

HeLa cells were stained with anti-HEC1/HEC (ab2613; in green) and DAPI (blue) in panel 1, and with anti-HEC1/HEC (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/HEC 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.
