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.

| FH Ankush (Verified Customer) (05-02-2025) | worked fine 
  | 
| FH Gabriele (Verified Customer) (01-12-2023) | The antibody works very well with our IF protocol. Maybe the dilution could be pushed to 1:500-1:600. TUBB3 1:400 (green), Hoechst (Blue) 
  | 
| FH Alessandro (Verified Customer) (07-27-2022) | No aspecific staining, great outcome 
 | 
| FH Josh (Verified Customer) (12-18-2018) | 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. Image caption: Differentiated adult hippocampal neural stem cell culture. BIII tubulin 1:500 (purple), S100 1:500 (red), Hoechst (blue). Scale bar = 20 um.
