General description

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

Synthetic peptide corresponding to human Tubulin β-III.

Physical form

Protein G Purified

Purified mouse monoclonal IgG1 conjugated to Alexa Fluor® 555 in PBS with 0.1% sodium azide and 15 mg/mL BSA.


Evaluated by Immunocytochemistry in rat E18 primary cortex cells.

Immunocytochemistry Analysis: A 1:100 dilution of this antibody detected Tubulin β-III in rat E18 primary cortex cells.


This antibody reacts with the C-terminus of the beta-III isoform of tubulin, which is known to be neuron specific. Does not identify beta tubulin found in glial cells.

Storage and Stability

Maintain refrigerated at 2-8 °C protected from light in undiluted aliquots for up to 6 months from date of receipt.

Target description

The unconjugated parent antibody (Cat. No. MAB1637) has an observed molecular weight at ~55 kDa
