  • Function

    Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain.
  • Sequence similarities

    Belongs to the tubulin family.
  • Post-translational

    Some glutamate residues at the C-terminus are polyglutamylated. This modification occurs exclusively on glutamate residues and results in polyglutamate chains on the gamma-carboxyl group. Also monoglycylated but not polyglycylated due to the absence of functional TTLL10 in human. Monoglycylation is mainly limited to tubulin incorporated into axonemes (cilia and flagella) whereas glutamylation is prevalent in neuronal cells, centrioles, axonemes, and the mitotic spindle. Both modifications can coexist on the same protein on adjacent residues, and lowering glycylation levels increases polyglutamylation, and reciprocally. The precise function of such modifications is still unclear but they regulate the assembly and dynamics of axonemal microtubules.
    Acetylation of alpha chains at Lys-40 stabilizes microtubules and affects affinity and processivity of microtubule motors. This modification has a role in multiple cellular functions, ranging from cell motility, cell cycle progression or cell differentiation to intracellular trafficking and signaling.

  • ICC/IF image of ab7750 stained HeLa cells. The cells were 4% formaldehyde 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 (ab7750, 5µg/ml) overnight at +4°C. The secondary antibody (green) was anti-mouse DyLight® 488 (ab96879) used at a 1/250 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.

  • Ab7750 staining human normal skin. Staining is localised to the cytoplasm.
    Left panel: with primary antibody at 2 ug/ml. Right panel: isotype control.
    Sections were stained using an automated system at room temperature. Sections were rehydrated and antigen retrieved with a retrieval buffer EDTA pH 9.0 . Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes and detected with an amplification kit for 30 minutes. Colorimetric detection was completed with diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

  • Overlay histogram showing HEK293 cells stained with ab7750 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton 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 (ab7750, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was anti-mouse DyLight® 488 (ab96879) at 1/500 dilution for 30 min at 22°C. 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. This antibody gave a positive signal in HEK293 cells fixed with methanol (5 min)/permeabilized in 0.1% PBS-Triton used under the same conditions.

Thank you for contacting us and reporting the problems you have encountered in using the anti-alpha Tubulin antibody [TU-01] (ab7750).

I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

As tubulin is the major building block of microtubules and is present in most eukaryotic cells there is a wide range of samples you could use as a positive control. If you have any human or mouse cell lines available such as HeLa or NIH-3T3 these should work well. Otherwise most tissue samples should also be positive, we have used both heartand skin tissue with this particular antibody.

If you would like I can take a look at the protocol you have been using and the results you have found in order to see if there are any changes I could suggest in order to improve the results observed so far. If you would like for me to do this, please could you fill out thequestionnaire I have attached to this email. If you could include any images you have of the blots performed that would be very helpful.

I look forward to receiving your reply.
