Scientific Data Images for alpha Tubulin Antibody (YOL1/34) - BSA Free

Western Blot: alpha Tubulin Antibody (YOL1/34) [NB100-1639] - Total protein from human HeLa and A431, mouse 3T3 and rat PC12 cell lines was separated on a 12% gel by SDS-PAGE, transferred to PVDF membrane and blocked in 5% non-fat milk in TBST. The membrane was probed with 2.0 ug/ml anti-alpha Tubulin in block buffer and detected with an anti-mouse HRP secondary antibody using West Pico PLUS chemiluminescence detection reagent. Alpha tubulin molecular weight: 50 kDa.
Immunocytochemistry/Immunofluorescence: alpha Tubulin Antibody (YOL1/34) - BSA Free [NB100-1639] - A431 cells were fixed in 4% paraformaldehyde for 10 minutes and permeabilized in 0.05% Triton X-100 in PBS for 5 minutes. The cells were incubated with alpha Tubulin Antibody [YOL1/34] (NB100-1639) at 1ug/ml overnight at 4C and detected with an anti-rat DyLight 488 (Green) at a 1:1000 dilution for 60 minutes. Nuclei were counterstained with DAPI (Blue). Cells were imaged using a 100X objective and digitally deconvolved.
Flow (Intracellular): alpha Tubulin Antibody (YOL1/34) [NB100-1639] - An intracellular stain was performed on HeLa cells with Tubulin [YOL1/34] Antibody NB100-1639 (blue) and a matched isotype control (orange). Cells were fixed with 4% PFA and then permeabilized with 0.1% saponin. Cells were incubated in an antibody dilution of 1.0 ug/mL for 30 minutes at room temperature, followed by Rat IgG (H+L) Cross-Adsorbed Secondary Antibody, Dylight 488.

Background: alpha Tubulin

Tubulin is the major building block of microtubules. Microtubules function as structural and mobile elements in mitosis, intracellular transport, flagellar movement and in the cytoskeleton. The tubulin superfamily is composed of six distinct families. Genes from the alpha, beta and gamma tubulin families are found in all eukaryotes. Microtubules of the eukaryotic cytoskeleton perform essential and diverse functions and are composed of a heterodimer of alpha and beta tubulins. Alpha and beta tubulin dimers are assembled to 13 protofilaments that form a microtubule of 22 nm diameter with a theoretical molecular weight of 50 kDa.

Tyrosine ligase adds a C-terminal tyrosine to monomeric alpha tubulin. Assembled microtubules can again be detyrosinated by a cytoskeleton associated carboxypeptidase. Detyrosinated alpha tubulin is referred to as Glu-tubulin. Another post-translational modification of detyrosinated alpha tubulin is C-terminal polyglutamylation which is characteristic for microtubules in neuronal cells and the mitotic spindle.

Like GAPDH and beta-actin, alpha/beta tubulin is often used as a loading control in immunoblot applications (1). Alpha/beta tubulin is also good for counterstaining microtubules in immunofluorescence (2).
