General description

Monoclonal Anti-Acetylated Tubulin (mouse IgG2b isotype) is derived from the hybridoma 6-11B-1 produced by the fusion of mouse myeloma cells and splenocytes from a mouse immunized with acetylated tubulin from the outer arm of Strongylocentrotus purpuratus (sea urchin). Tubulin is a heterodimer, which consists of a-tubulin and b-tubulin; both subunits have a molecular weight of 50,000 and share considerable homology.
α-tubulin, also called as tubulin α 4a (TUBA4A), is mapped to human chromosome 2q35. The gene codes for a member of the α -tubulin family containing 448 amino acids. TUBA4A belongs to the subfamily of tubulin, which is the major building block of microtubules. α-subunit of tubulin has molecular weight of 50,000.


The antibody has been used to detect acetylated α-tubulins from many organisms including protista, plants, invertebrates, and vertebrates. The antibody recognizes an epitope located on the α3 isoform of Chlamydomonas axonemal α-tubulin, within four residues of Lys40 when this amino acid is acetylated. A sequence very similar to the one detected by the antibody in Chlamydomonas is found in the majority of α-tubulins, but the corre­sponding region is markedly divergent in some α-tubulin isoforms from chicken, Drosophila, and yeast. Occasionally, the epitope recognized by the antibody may be absent or masked, as it is in the rat kangaroo epithelial-like cell line PtK2.

Monoclonal Anti-Acetylated Tubulin antibody produced in mouse has also been used in quantitative dot blot, immunofluorescence, Western blot, immunocytochemistry, enzyme linked immunosorbent assay (ELISA), solid phase radioimmunoassay (RIA) and electron microscopy.

Biochem/physiol Actions

Acetylated tubulin is associated with axoneme assembly in a variety of organisms. Acetylated tubulin might play a crucial role in the differentiation of microtubule structure and function. Post translational modification of α-tubulin i.e. the reversible addition of an acetyl group to Lys40, by specific acetylase, results in acetylated tubulin.
