Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Acetyl-α-Tubulin (Lys40) Antibody detects endogenous levels of tubulin only when acetylated at Lys40. This amino acid is not conserved in β-tubulin.

Acetyl-α-Tubulin (Lys40) Antibody检测仅在Lys40位点乙酰化的内源性tubulin蛋白。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Lys40 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).


The Elongator complex catalytic subunit (Elp3) acetylates α-tubulin at Lys40 while the histone deacetylase HDAC6 functions as a tubulin deacetylase. This post-transcriptional modification may be required for dynamic cell shape remodeling, cell motility, tubulin stability and terminal branching of cortical neurons (2-3).

elongator 复合物的催化亚基(Elp3)使α-tubulin蛋白在Lys40位点乙酰化,然而组蛋白脱乙酰酶HDAC6的功能是tubulin蛋白的脱乙酰酶。这个转录后修饰可能对动态的细胞形态的重塑、细胞能动性、tubulin稳定性和皮层神经元的终端分支是需要的(2-3)。
