ab7291 staining alpha-Tubulin in Caco-2 cells. The cells were fixed with 100% methanol (5min) and then blocked in 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated with ab7291 at 1μg/ml and ab6046 at 1µg/ml overnight at +4°C, followed by a further incubation at room temperature for 1h with an anti-mouse AlexaFluor® 488 (ab150117) at 2 μg/ml (shown in green) and anti-rabbit AlexaFluor® 594 (ab150088) at 2 μg/ml (shown in pseudo color red). Nuclear DNA was labelled in blue with DAPI.Negative controls: 1– Rabbit primary antibody 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.

ICC/IF image of ab7291 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab7291, 1µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).

Immunofluorescent imaging of human cells (U2OS) with ab7291 reveals a delicate network of alpha-tubulin (green) located exclusively in the cytoplasm. The nucleus is stained blue.IF was performed with a standard paraformaldehyde technique (fixed in PBS buffered PFH 4% for 5 minutes, permeabilised with 0.5% triton-PBS for 5 minutes, blocked with 5% milk / 0.2% tween for one hour.  Primary antibody used at 1/200 in 5% milk / 0.2% TWEEN for one hour, secondary antibody Alexa 488 for 30 minutes.  All blocking and incubation steps carried out at 37 degrees.Unfortunately, due to size constraints for images on our website, we are unable to show the full uncompressed picture in all its glory!

An Alexa-Fluor ® 488 conjugated goat anti-mouse antibody was used as the secondary. The image shows alpha tubulin staining in green and DAPI counterstain in blue.See Abreview

Overlay histogram showing HeLa cells stained with ab7291 (red line). The cells were fixed with 80% methanol (5 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 (ab7291, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was an anti-mouse DyLight® 488 (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

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. This antibody also gave a positive result in 100% methanol fixed (5 min) Hek293, HepG2 and MCF7 cells at 1µg/ml, and in 4% formaldehyde fixed (10 min) HeLa, Hek293, HepG2 and MCF7 cells at 1µg/ml.
