General description

Tubulin is the major building block of microtubules. This intracellular cylindrical filamentous structure is present in almost all eukaryotic cells. Microtubules function as structural and mobile elements in mitosis, intracellular transport, flagellar movement, and in the cytoskeleton. Tubulin is a heterodimer, which consists of α-tubulin and β-tubulin; both subunits have a molecular weight of 55 kDa and share considerable homology. The most studied tubulins have been isolated from vertebrate brains. The microtubules can be viewed in immunofluorescent microscopy, which enables the observation of the intracellular organization of proteins that are in the form of a supramolecular structure.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4 containing 1% bovine serum albumin and 15 mM sodium azide.


The antibody recognizes all five isoforms of β-tubulin (β1-β5). It reacts with the β-Lc and β-Sc fragments in the carboxy-terminal part of β−tubulin in immunoblotting. The antibody may be used to localize β−tubulin in cultured cells or tissue sections.


FITC-β tubulin antibody may be used for detection ajnd localization of β-tubulin by direct labeling in a variety of eukaryotic cells ranging from human embryonic kidney cells (HEK293T) to cells of azuki bean epicotyl. by immunohistochemical and immunocytochemical assays.

Antibodies to Tubulins, including Centrosome-Associated ε-Tubulin

Microtubules of the eukaryotic cytoskeleton are composed of a heterodimer of α- and β-tubulin. In addition to α-and β-tubulin, several other tubulins have been identified, bringing the number of dist...
