Monoclonal Anti-Tyrosine Tubulin (mouse IgG3 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Tubulin as a cylindrical filamentous structure and is present in almost all eukaryotic cells. Tubulin is a heterodimer which consists of α-tubulin and β-tubulin; both subunits have a molecular weight of 55 kDa and share considerable homology.

The intracellular cylindrical filamentous structure, microtubules is mainly made up of tubulin and is present in all eukaryotic cells. Monoclonal Anti-Tyrosine antibody can be used in immunocytochemical localization of tyrosinated α tubulin by indirect immunofluorescence labelling. Monoclonal Anti-Tyrosine antibody reacts specifically with tyrosine tubulin of bovine brain, African Green Monkey kidney cells (Vero), dog kidney (MDCK), marsupial kidney (Potoroo, PtK2), mouse pituitary tumour (AtT-20), yeast, and Xenopus.

The antibody reacts against tubulin′s C-terminal tyrosine in immunoblotting assays and may be used for localization of this epitope in cultured cells or tissue sections.

peptide containing the carboxy-terminal amino acids of α-tubulin

Monoclonal Anti-Tyrosine Tubulin has been used in:

• indirect immunofluorescent labelling
• immunoblotting technique
• immunocytochemical staining

Tubulin acts as a major building block of microtubules. Tubulin tyrosinylation is involved in the assembly status of tubulin. A specific tubulinyl tyrosine carboxypeptidase removes the terminal tyrosine to yield an α-tubulin terminating in a glutamic acid residue while another enzyme modifies the α-tubulin by addition of tyrosine to the carboxy terminus to offer a potential cycle of tyrosine addition and loss.
