  • Peptide Competition and Phosphatase Treatment
    Lysates prepared from MDCK cells treated with staurosporine (1) or left untreated (2-6) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were either left untreated (1-5) or treated with lambda phosphatase (6), blocked with a 5% BSA-TBST buffer for one hour at room temperature, and incubated with the ab12866 antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with: no peptide (1, 2, 6), the non phosphopeptide corresponding to the immunogen (3), a generic phosphoserine-containing peptide (4) or, the phosphopeptide immunogen (5). After washing, membranes were incubated with goat F(ab)2 anti-rabbit IgG HRP conjugate and bands were detected using the Pierce SuperSignal method. The data show that only the peptide corresponding to cofilin [pS3] blocks the antibody signal. The data also show that phosphatase stripping eliminates the signal, verifying that the anti
  • ICC/IF image of ab12866 stained MCF7 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab12866, 1µg/ml) overnight at +4°C. 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) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of oral squamous cell carcinomas (OSCCs) surgical margin labeling Cofilin (phospho S3) with ab12866 at 1/300 dilution. After deparaffinization in xylene and rehydration in graded ethanol, antigen epitope retrieval was performed using 10 mM citrate buffer, pH 6.0 in a vapor cooker. Endogenous peroxidase activity was blocked with 3% hydrogen peroxide for 15 min. Rabbit polyclonal anti-cofilin (phospho S3) (ab12866, 1/300) was incubated overnight at 8°C followed by addition of the secondary antibody and streptavidin-biotin peroxidase. Color of reaction product was developed by 3,3′-diaminobenzidine (DAB) and counterstaining was performed with hematoxylin.

    Nuclear staining for Cofilin (phospho S3) is evident in the more basal layers of epithelium in surgical margin tissue compared to OSCCs tissue.

  • Immunocytochemistry/ Immunofluorescence analysis of human neuroblastoma cells labeling Cofilin (phospho S3) with ab12866 at 1/500 dilution. Cells were fixed in paraformaldehyde, permeabilized for 15 minutes in 0.01% Triton X-100, blocked using 5% serum for 30 minutes at 20°C, then incubated with ab12866 at a 1/500 dilution for 2 hours at 20°C. The secondary used was a Dylight 488 conjugated donkey anti-rabbit IgG (H+L) used at a 1/500 dilution.

  • Flow Cytometry analysis of U-87 MG cells labeling Cofilin (phospho S3) with ab12866. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with Anti-Cofilin (phospho S3) antibody (ab12866, red) or with rabbit isotype control (pink) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody at a dilution of 1/400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.
