Background Information

TUBB3, the class III β tubulin or Tuj1, is selectively expressed in testis and neurons of the central and peripheral nervous system. It has been widely used as a marker for neurons. Aberrant expression of TUBB3 has also been found in various tumors of non-neural origin and can be used as a biomarker for cancer aggressiveness and a marker for the tendency to respond poorly to chemotherapy. This antibody is specific to TUBB3 but not cross-react with other tubulin isoforms.

BIII tubulin antibody signal nicely fills neuronal cell bodies and processes with good signal to noise at a reasonable dilution (1:500 in 1% NDS, 0.3% Triton-X, PBS with donkey anti-mouse 647 secondary, 1:500). However, BIII tubulin antibody signal also colocalized with S100 immunoreactive astrocytic processes, though with a lesser intensity. Overall, the antibody is a useful marker of neuronal differentiation when used in combination with other cell-selective antibodies and morphology.
