Tubulin is one of several members of a small family of globular proteins. The most common members of the tubulin family are α-tubulin and β-tubulin, the proteins which makes up microtubules. Each has a molecular weight of approximately 55 kDa. Microtubules are assembled from dimers of α- and β-tubulin. These subunits are slightly acidic with an isoelectric point between 5.2 and 5.8. Tubulin was long thought to be specific to eukaryotes. Recently, however, the prokaryotic cell division protein FtsZ was shown to be evolutionarily related to tubulin.

Expected to cross-react with Avian, Porcine (Pig), Rat, Bovine, Sheep, Human, Monkey. Reactivity with other species has not been confirmed.

The antibody reacts with the C-terminus of the neuron specific beta III isoform of tubulin. Does not identify beta tubulin found in glial cells.

A synthetic peptide corresponding to amino acids 443-450 (ESEAQGPK) of human class III beta-tubulin conjugated to KLH.

Epitope: C-terminus

Mouse monoclonal IgG1 ascites in buffer containing PBS containing 1% BSA and 15 mM sodium azide.

Unpurified

Stable for 1 year at -20°C in undiluted aliquots from date of receipt.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Control
Positive control: Brain tissue or neurons of any type.
Negative control: Non neural tissue or Astrocytes.
