Tubulin beta localization in Arabidopsis thaliana epidermis cells. Tubulin beta localized to division plates visualized in green, nucleus with DAPI in blue. Plant material has been fixed in para-formaldehyde for 30 minutes. Tissue cleaning has been performed before immunolocalization. Primary antibodies: Agrisera anti-tubulin beta priamry antibody in dilution 1: 1000 and Agrisera goat anti-rabbit IgG DyLight® 488, secondary antibody in dilution 1: 2000. Scale bar – 10 µm.
(A) The 3 days old suspension cells of Arabidopsis thaliana have been fixed for 25 minutes with 2% FA, cell wall was partaillly digested with 0.2% Dricelase in MES buffer (pH 5.1) for 30 min at 37°C and the cells were dried on coated slide to omit PM extraction. Following by incubation for 45 minutes with Agrisera anti-tubulin beta chain primary antibody in a dilution of 1: 1000, washing once and 45 min incubation with a secondary goat anti-rabbit Alexa 555 antibody, in a dilution of 1:1000 dilution (Invitrogen). Cells were counterstained witn DAPI and visialized under epi/fluiresecnet microscope (B).

Please, note that tubulin beta is only detected in actively dividing meristematic cells (see immunolocalization image below). Therefore to allow detection on a western blot, analyzed material must contain enough meristematic cells with dividing activity.
Signal in a western blot application in Chlamydomonas reinhardtii is obtained with a load of 100 µg/well and a dilution of 1: 500.
Tubulin beta (TUB) together with alpha tubulin is making up microtubules.
