Anti-beta III Tubulin antibody [EP1569Y] (ab52623)

ab52623 staining beta III Tubulin in wild-type HAP1 cells (top panel) and TUBB3 knockout HAP1 cells (bottom panel).

The cells were fixed with 100% methanol for 5 minutes, 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 1 hour. The cells were then incubated with ab52623 at 1/500 dilution and ab195889 at 1/250 dilution (shown in pseudocolour red) overnight at +4°C, followed by a further incubation at room temperature for 1 hour with a goat secondary antibody to Rabbit IgG (Alexa Fluor^® 488) (ab150081) 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).

Lane 1: Wild type HAP1 whole cell lysate (20 µg)
Lane 2: beta III Tubulin knockout HAP1 whole cell lysate (20 µg)
Lane 3: HeLa whole cell lysate (20 µg)
Lane 4: HEK293 whole cell lysate (20 µg)

Lanes 1 - 4: Merged signal (red and green). Green - ab52623 observed at 52 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab52623 was shown to specifically react with beta III Tubulin in wild-type cells as signal was lost in beta III Tubulin knockout HAP1 cells. Wild-type and beta III Tubulin knockout samples were subjected to SDS-PAGE. Ab52623 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively.

Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

In vivo, CK1δ T347 is phosphorylated in trans.

D) Phosphorylation of CK1δ at T347 is not dependent on CK1 activity. HEK-293 cells over-expressing wild-type CK1δ were treated with CK1 inhibitors PF670462 (PF670, 1 μM), PF4800567 (PF480, 1 μM), or D4476 (30 μM) for 3 hours, followed by addition for 30 min of either DMSO or 40 nM Calyculin A. Cell lysates were immunoblotted for anti-pT347 or anti-Myc antibodies. CK1 inhibitors block the autophosphorylation-induced mobility shift but do not decrease phosphorylation of T347. Myc-tagged CK1δ indicated by curly brackets. ab52623 lower panel.

ab52623 staining beta III Tubulin in NGF-differentiated PC-12 (Rat adrenal gland pheochromocytoma cell line) cells.

The cells were fixed with 100% methanol (5 minutes) and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1 hour. The cells were then incubated with ab52623 at 5 μg/ml and ab7291 at 1 µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1 hour with an AlexaFluor^®488 Goat anti-Rabbit secondary (ab150081) at 2 μg/ml (shown in green) and AlexaFluor^®594 Goat anti-Mouse secondary (ab150120) at 2 μg/ml (shown in pseudo color red). Nuclear DNA was labeled in blue with DAPI.
Negative controls: 1– Rabbit primary and anti-mouse secondary antibody; 2 – Mouse primary antibody and anti-rabbit secondary antibody. Controls 1 and 2 indicate that there is no unspecific reaction between primary and secondary antibodies used.

Overlay histogram showing U-87 MG (Human glioblastoma-astrocytoma epithelial cell line) cells stained with ab52623 (red line).

The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Triton X-100 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 (ab52623, 1/1000 dilution) for 30 min at 22ºC. The secondary antibody used was Alexa Fluor^® 488 goat anti-rabbit IgG (H&L) (ab150081) at 1/2000 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (ab172730, 0.1 μg/1x10⁶) used under the same conditions. Unlabeled sample (blue line) was also used as a control.

Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

This antibody gave a positive signal in U-87 MG cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

IHC-Fr image of Beta III Tubulin staining on zebrafish retina sections using ab52623 (1:100).

The sections were fixed with paraformaldehyde and permeabilized using Triton-X. Antigen retrieval was performed using Tris-HCl. Blocking was perfomed using 5% BSA for 1 hour at 23°C. ab38738 was diluted 1:100 and incubated with the sections for 16 hours at 4°C. The secondary antibody was goat polyclonal to rabbit IgG conjugated to Alexa Fluor^®488 (1:1000).

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab52623 overnight at 4°C.

Antibody binding was detected using ab175781 at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx.

Cells were fixed with 4% paraformaldehyde and permeabilized with 90% methanol. An Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (1/2000) was used as the secondary antibody. Black - Isotype control, rabbit monoclonal IgG. Blue - Unlabeled control, cells without incubation with primary and secondary antibodies.
