sarkosyl-resistant ribbons from Strongylocentrotus purpuratus (sea urchin) sperm axonemes.


The antibody recognizes the two major and one of the minor β‑tubulin isotypes of the free-living soil nematode C. elegans. It also binds to Sarkosyl-resistant ribbons from Strongylocentrotus purpuratus sperm axonemes, to neuronal axons of the larva of an ascidian (Ciona intestinalis) and to tubulin of chicken and mammals, cultured human fibroblasts, bovine and rat brain tissue. In C.elegans preparations, the antibody does not recognize tubulin that has been heat denatured in the presence of SDS and β-mercaptoethanol, though it is bound to tubulin separated on isoelectric focusing gels. It reacts with heat-denatured and reduced mammalian preparations in immunoblotting.
