Protocol Available protocols: Western Blotting, Immunohistochemistry (Paraffin) Specificity / Sensitivity alpha-Tubulin Antibody detects endogenous levels of total α-tubulin protein, and does not cross-react with recombinant β-tubulin. Species Reactivity: Human, Mouse, Rat, Monkey, D. melanogaster, Bovine Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the sequence of human α-tubulin. Antibodies are purified by protein A and peptide affinity chromatography. Background The cytoskeleton consists of three types of cytosolic fibers: microtubules, microfilaments (actin filaments), and intermediate filaments. Globular tubulin subunits comprise the microtubule building block, with α/β-tubulin heterodimers forming the tubulin subunit common to all eukaryotic cells. γ-tubulin is required to nucleate polymerization of tubulin subunits to form microtubule polymers. Many cell movements are mediated by microtubule action, including the beating of cilia and flagella, cytoplasmic transport of membrane vesicles, chromosome alignment during meiosis/mitosis, and nerve-cell axon migration. These movements result from competitive microtubule polymerization and depolymerization or through the actions of microtubule motor proteins (1).
