General description

Microtubules are composed of tubulin and several additional proteins designated microtubule associated proteins (MAPs). Tubulin is a heterodimer which consists of an α-chain and a β-chain, both of which have a molecular weight of approximately 55,000. Microtubules form an elaborate cytoplasmic network during interphase and are reorganized into the mitotic spindle during cell division.

Tubulin is an extremely conserved and negatively charged protein. It is expressed in all eukaryotic cells, but mainly in brains.


The product stains tubulin in cultured chicken fibroblasts or 3T3 mouse fibroblasts. Additional bands may be stained in immunoblotting.


microtubule proteins from brains of 13 day old chicken embryos


Anti-Tubulin antibody produced in rabbit has been used in immunoblotting and indirect immunofluorescence.

Biochem/physiol Actions

αβ-tubulin heterodimers helps in formation of microtubules. Tubulin dimers exhibits GTPase activity, assembly and disassembly properties. It facilitates the construction of the flagellar apparatus.

Antibodies to Tubulins, including Centrosome-Associated ε-Tubulin

Microtubules of the eukaryotic cytoskeleton are composed of a heterodimer of α- and β-tubulin. In addition to α-and β-tubulin, several other tubulins have been identified, bringing the number of dist...
