重组Anti-beta Catenin抗体[E247] - ChIP Grade (ab32572)

Lanes 1 - 4: Merged signal (red and green). Green - ab32572 observed at 95 kDa. Red - loading control, ab8245 observed at 37 kDa.

 ab32572 was shown to react with beta Catenin in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab255352 (knockout cell lysate ab263756) was used. Wild-type and beta Catenin knockout samples were subjected to SDS-PAGE. ab32572 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 5000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Chromatin was prepared from HCT 116 cells according to the Abcam Dual-X-ChIP protocol*. Cells were fixed with 1.5 mM EGS for 30 mins and then formaldehyde for 10 min.

The ChIP was performed with 25 µg of chromatin, 5 µg of ab32572 (red), or 5 µg of rabbit normal IgG ab172730 (gray) and 20 µl of Protein A/G sepharose beads. The immunoprecipitated DNA was quantified by real time PCR (Taqman approach for active and inactive loci, Sybr green approach for heterochromatic loci)

ab32572 staining in CTNNB1 (beta Catenin) wild-type HAP1 cells (top panel) and in CTNNB1 (β-catenin) knockout HAP1 cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab32572 at 1/250 dilution and ab195889 at 1/250 dilution (shown in pseudocolour red) overnight at +4°C, followed by a further incubation at room temperature for 1h with Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) secondary antibody at 2 μg/ml (shown in green). Nuclear DNA was labeled in blue with DAPI.

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

beta Catenin was immunoprecipitated from 0.35 mg A431 (Human epidermoid carcinoma epithelial cell) whole cell lysate with ab32572 at 1/50 dilution (2μg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab32572 1/500 dilution (2 μg/ml). VeriBlot for IP Detection Reagent (HRP) (ab131366) was used as the secondary antibody at 1/1000 dilution.

ab32572 staining beta Catenin in SW480 (Human colorectal adenocarcinoma cell line) cells treated with BIO (ab120891), by ICC/IF. Increase of beta Catenin expression correlates with increased concentration of BIO, as described in literature.
The cells were incubated at 37°C for 48h in media containing different concentrations of ab120891 (BIO) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab32572 (1/200) dilution was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed (ab96899) secondary antibody at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

Different expression level of beta Catenin in HCTs (hepatocellular carcinoma tissues) and PLTs (para-cancerous liver tissues).

The HCTs, PLTs were paraffin-embedded and cut into sections with 5 μm-thickness for hematoxylin-eosin and immunohistochemistry (IHC) analysis. ab32572 was used at a dilution of 1:400. The second antibody was a biotinylated IgG to incubate 40 minutes at 37°C. Finally, the tissue slices were visualized by the 3, 3-diaminobenzidine solution and counterstained with hematoxylin. Substitution of the primary antibody with phosphate-buffered saline was served as a control for IHC.

The beta Catenin with negative, weak, moderate and strong staining activity was respectively detected in HCTs (E-H) and PLTs (M-P). Section E shown above, for full image please see original paper.
