Anti-Tubulin β-III Antibody, clone TU-20, Alexa Fluor^™488 Conjugated

50 kDa

Tubulin is one of several members of a small family of globular proteins which polymerize to form cytoskeletal structures called microtubules. The most common members of the tubulin family are α-tubulin and β-tubulin. Tubulin dimers, typically composed of α- and β-tubulin subunits, assemble onto microtubules forming large polymers. β-III tubulin is a unique microtubule subunit that is found expressed almost exclusively in neurons. Due to the unique expression pattern of β-III tubulin it is often utilized as a marker to identify neuronal cells from other brain cells such as glia which do not express it. β-III tubulin also serves as a cytoarchitectural marker since it is primarily found within neurite extensions.

Epitope: C-terminus
