This antibody recognizes the C-terminal peptide sequence ESESQGPK (aa 441-448) of human class III β-tubulin specific for neurones. The antibody is a highly specific marker for neuronal tissue. TU-20 is very useful for the detection of microtubule structures on fixed cells. MAb TU-20 is widely cross-reactive among species (recognized epitope conserved within all species).

Background
The betaIII-tubulin isotype is present dominantly in cells of neuronal origin and it is one of the earliest marker of neuronal differentiation. Class III beta-tubulin, is regarded as a specific probe for the cells of neuronal origin as well as for the tumours originating from these cells. The neuron-associated class III beta-tubulin isotype is most abundant in cells of neuronal origin but was also detected in Sertoli cells of the testis and transiently in non-neuronal embryonic tissues.Synonyms: Tubulin beta-3 chain, Tubulin beta-4, Tubulin beta-III
