Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IHC-P=Immunohistochemistry (Paraffin), F=Flow Cytometry, IF-IC=Immunofluorescence (Immunocytochemistry),


Species predicted to react based on 100% sequence homology: Xenopus,

Specificity / Sensitivity

The α-Tubulin Antibody detects endogenous levels of total α-tubulin protein, and does not cross-react with recombinant β-tubulin.

α-Tubulin Antibody检测内源性α-tubulin总蛋白,而且不与重组的β-tubulin蛋白发生交叉反应。

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.

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).
