  • 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.

The FACS data on the datasheet was from cells stained with a purified version of the antibody for which the concentration was known to be 0.4 mg/ml. The antibody is currently produced as ascites fluid. The amount of specific antibody in ascites is typically 1 - 10 mg/ml.

A volume of 1.0 ul per 10e6 cells is a standard starting point for determining the optimal dilution of ascites for FACS, but you may need to adjust the amount up or down within a range of, for instance, 0.25 - 4 ul, depending on your initial results.

We would recommend using a pH6 sodium citrate retrieval.

Thank you for your enquiry.

I can confirm that ab24610 antibody is sold as ascites. Unpurified antibodies, such as those sold as whole antiserum, ascites or tissue culture supernatant will not have a concentration stated on the datasheet. Antibody concentration is usually determined by protein assay, and serum / ascites / tissue culture supernatant will contain a lot of other proteins, which means the antibody quantification would not be accurate.

I can confirm that for ascites, concentration of antibody is known to very between 5 - 10 mg/ml.

I am sorry we are not able to provide an exact concentration on this occasion, but hope this information will be helpful to you. If you have any further questions, please do not hesitate to contact us.

Thank you for your reply. I will be taking care of your query as Carolyn is out of the office.

I don't know enough about acetylated alpha Tubulin expression in primary cilium to be able to tell you for certain whether or not it is specific for primary cilium. Plus we do not have a protocol for ab24610 for specifically staining primary cilium. However, I did find that this clone has been cited as a marker for primary cilia in this article:

A quick literature search also suggests Adenyl Cyclase 3 (we carry ab125093 for this protein) may be a good marker for primary cilium. I'd recommend looking in the literature for more specific protocol recommendations.

I hope this information helps. Please contact us with any other questions.

Thank you for your patience. After checking with the lab, we are not completely sure what the bright green staining is. We suspect that these are recently divided cells and the staining we are seeing is clumps of tubulin as the cells are pulling apart. I hope this helps, please let me know if you need any additional information or assistance.

Thank you for contacting Abcam regarding ab24610.

Regarding the specificity of this antibody, it will recognize structures containing acetylated alpha-tubulin. In terms of structures stained, acetylated alpha tubulin is present in various microtubule structures and plays a role in stabilizing the structures of all microtubules.We expect the antibody will bind to primary cilia, centrioles, mitotic spindles, midbodies and to subsets of cytoplasmic microtubules in 3T3 and HeLa cells.

I hope this information is helpful. Please do not hesitate to contact me if you have any additional questions.

Thank you for contacting Abcam.

The Ascites storage buffer does not contain Sodium Azide and so you do not have to worry about that.

If there is anything else I can help you with, please let me know.

Thank you for contacting us and sorry for the delay in getting back to you.

I am now able to confirm that these antibodies are produced from the same clone 6-11B-1 and should produce very similar results. We have them separated into two different products as they are sourced from different places and this also means that we have slightly different information regarding their uses in different applications and species they have been used in.

I am sorry if the information has been confusing. If you have any further questions, please do not hesitate to contact us again.

Vielen Dank für Ihren Anruf.

Ich habe nun vom Labor die Antwort bekommen, dass der ab24610 leider noch nicht Verkaufsbereit ist. Unglücklicherweise, hatten wir viele Probleme mit diesem Antikörper und deshalb wird der Klon momentan gerade "subcloned". Falls ein Subklon dann positive ist, wird die Produktion aufgefahren. Auch falls alle Etappen positive ausfallen, wird dies jedoch mehrere Wochen dauern.

Es tut mir leid, Ihnen keine besseren Nachrichten geben zu können momentan. Ich kann Ihnen empfehlen, sich auf dem Datenblatt unter "email me" einzutragen. So werden Sie benachrichtigt, sobald der Antikörper wieder erhältlich ist. Click here (or use the following:

Bitte entschuldigen Sie all die Umstände. Bitte zögern Sie auch nicht, uns wieder zu kontaktieren, sollten Sie weitere Fragen oder Bedenken haben.
