General description

Microtubules are involved in a wide variety of cellular activities ranging from mitosis and transport events to cell movement and the maintenance of cell shape. Tubulin itself is a globular protein which consists of two polypeptides (alpha and beta tubulin). Alpha and beta tubulin dimers are assembled to 13 protofilaments that form a microtubule of 22 nm diameter. Tyrosine ligase ads a C-terminal tyrosin to monomeric alpha tubulin. Assembled microtubules can again be detyrosinated by a cytoskeleton associated carboxypeptidase. Detyrosinated alpha tubulin is referred to as Glu-tubulin. Another post-translational modification of detyrosinated alpha tubulin is C-terminal polyglutamylation which is characteristic for microtubules in neuronal cells and the mitotic spindle.


Peptide corresponding to the C-terminal of Glu tubulin.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.


The antibody specifically recognizes the detyrosinated form (Glu tubulin) of the tubulin alpha chain (Bianchi, M., 2006; Goulimari, P., 2005).

Physical form

Affinity purified immunoglobulin

Purified rabbit polyclonal in buffer containing liquid PBS.

Storage and Stability

Stable for 6 months at -20°C in undiluted aliquots from date of receipt.

Handling Recommendations:
Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
