alpha Tubulin Antibody Summary

Immunogen
A synthetic peptide derived from C-terminus of human tubulin alpha.
Localization
Cytoplasm
Marker
Microtubule Marker
Specificity
Microtubules, the major cytoskeletal elements found in all eukaryotic cells, consist of tubulin, which is a dimer of two 55kDa subunits: alpha and beta. Microtubules play key roles in chromosome segregation in mitosis, intracellular transport, ciliary and flagellar bending, and structural support of the cytoskeleton.

Background

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 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.

FAQs for alpha Tubulin Antibody (NBP1-36648). (Showing 1 - 6 of 6 FAQ).

  1. Our customer want to know which tubulin (alpha or beta) is suitable for WB as the loading control in brain tissue. Could you recommend the tubulin alpha or beta as a loading control for WB in brain tissue? In case of adipose tissue, tubulin alpha is not suitable as a loading control. How about in brain tissue? Could you let me know?
    • Both beta and alpha tubulin are expressed in the brain, and either one would make a suitable loading control. Beta tubulin may give a cleaner signal than alpha, but this varies greatly. You may wish to consider NB600-936.
  2. We are working with mouse liver tissue, will this alpha tubulin antibody work as a loading control?
    • Yes, alpha tubulin is expressed in nearly all tissue types including liver; however we do not recommend using as a loading control antibody in stomach or oral mucosa tissue as expression of alpha tubulin in these areas is minimal.
  3. Will your alpha tubulin antibody work as a loading control for simple western?
    • Yes, this alpha tubulin antibody has been validated in simple western and makes an excelent loading control antibody. Simple western has a lower detection limit of 12kDA and alpha tubulin detects around 55kDA.
  4. Will this alpha tubulin antibody recognize both isoforms of alpha tubulin?
    • The epitope for this alpha tubulin antiboyd lies on the C-terminus of the protein and the difference between the two major isoforms is witin the first 35 aa of the N-terminus so this alpha tubulin antibody will recognize both isoforms.
  5. We're looking at LC3B, aSYN and p62 which are 18, 23 and 65 kDA respectively so we need the loading control antibody to be between those.
    • Alpha tubulin antibody detects around 55kDA so that would be a good option for a loading control antibody for those targets as you should be able to easily distinguish from the other bands.
  6. I am looking for a primary alpha tubulin  antibody that is conjugated to a red fluorophore.
    • Okay, our most popular alpha tubulin antibody is NB100-690 and is available in a variety of formats. So if you are looking for red I would recommend a DyLight 550, 650 etc.
