Recommended Usage:

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.06 µg per million cells in 100 µl volume. For immunohistochemical staining on frozen tissue sections, the suggested use is 1.25-5 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633 nm / 635 nm.

Human lung adenocarcinoma cell line

Human lung adenocarcinoma cell line A549 was treated with Fixation Buffer (Cat# 420801) and Permeabilization Wash Buffer (Cat# 421002), and then stained with TUBB3 (clone AA10) Alexa Fluor® 647 (filled histogram) or mouse IgG2a, κ Alexa Fluor® 647 isotype control (open histogram).

C57BL/6 mouse frozen brain tissue

C57BL/6 mouse frozen brain tissue was fixed with 4% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5 % Triton X-100 for ten minutes, and blocked with 5% FBS for 1 hour. Then the tissue was stained with 1.25 µg/ml of Alexa Fluor® 647 anti-Tubulin Beta 3 (TUBB3) (Clone AA10) (shown in red) and 5 µg/ml of Alexa Fluor® 488 anti-GFAP (Clone 2E1.E9) (shown in green) in blocking buffer, overnight at 4°C. Nuclei were counterstained with DAPI (blue). The image was captured with 10X objective.


Tubulin is the main component of microtubules. In adults, tubulin beta 3 (TUBB3) is primarily expressed in neurons and is commonly used as a neuronal marker. It plays an important role in neuronal cell proliferation and differentiation. Mutations in this gene cause congenital fibrosis of the type 3 extraocular muscles. Tubulin beta 3 (TUBB3) is also found in a wide range of tumors. Studies indicate that it is a predictive and prognostic marker in various tumors.
