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 adds a C-terminal tyrosin to monomeric alpha tubulin. Assembled microtubules can 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.

Western Blotting Analysis: A representative lot from an independent laboratory specifically detected nontyrosinated alpha Tubulin and not tyrosinated alpha Tubulin from purified porcine alpha Tubulin (Gundersen, G. G., et al. (1984). Cell. 38(3):779-89.).
ELISA Analysis: A representative lot from an independent laboratory specifically detected nontyrosinated alpha Tubulin, and not nontyrosinated alpha Tubulin in an indirect ELISA and in a competitive ELISA (Gundersen, G. G., et al. (1984). Cell. 38(3):779-89.).
Immunocytochemistry Analysis: A representative lot from an independent laboratory specifically detected nontyrosinated alpha Tubulin, and not nontyrosinated alpha Tubulin in TC-7 cells in interphase (Gundersen, G. G., et al. (1984). Cell. 38(3):779-89.).
Biochem/physiol Actions
This antibody detects the nontyrosinated form of alpha Tubulin.
Physical form
Rabbit polyclonal serum in buffer containing serum with 0.05% sodium azide.
Unpurified
Preparation Note
Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt 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.
Analysis Note
Evaluated by Western Blotting in NIH/3T3 cell lysate, which were untreated or treated with Pancreatic Carboxypeptidase (PCA).
Western Blotting Analysis: A 1:2,000 dilution of this antibody detected alpha Tubulin, nontyrosinated in 10 µg of PCA treated NIH/3T3 cell lysate and demonstrated a loss of signal in untreated NIH/3T3 cell lysate.
